Moving on, and sideways, from yesterday’s Regional Text Google Chart Data via Country Code Tutorial, today, we wanted the user to be able to better control the text look of these Google Chart Geo Charts presented with these Regional Maps, as much as anything, starting with …

It’s ongoing, but many data related problems with our Regional Map creations got sorted today. You rarely go wrong with data when it is “indexed” by numerical data, but we were required to compare one data set of regional names with another, and when you compare strings with strings, problems are bound to happen on occasions. We start, instead, not being so stringent on mismatches of names of more than one word, if a first word match is found. While we sort this out we warn in the prompt window blurb of this, in a changed latest draft image_venn.html Google Chart Image Chart Venn Chart or Scatter Chart or GraphViz Chart or Pie Chart or Line Chart or Bar Chart or Candlestick/Box Chart or Google-O-Meter Chart or Radar Chart or Map Chart interfacing web application you can also try below.

User entries can accept a comma separated list of ISO-3166 two letter character codes now, though we prefer to still think in terms of Google Chart Image Chart tendencies with the vertical bar ( ie. | ) syntax.

Another issue happened with apostrophies in the Region Names we have remedied onto yesterday’s Regional Text Google Chart Iframe via Country Code Tutorial.

Better than yesterday’s Regional Text Google Chart Map Charts via Country Code Tutorial‘s use of …

• popup windows … if the recipient URLs share the same domain we prefer …
• iframe

… webpage hosting, because that way you can use that one web browser tab performing a multiple country scenario. You’ll see this as a really pronounced improvement on mobile platforms, where the navigating between web browser tabs is harder to manage.

And it occurred to us that the title for yesterday’s incarnation of the “multiple country scenario” Google Charts Map Chart was pretty vanilla, and more use can happen if in that title we list country names involved. Sounds easy, doesn’t it? Well, we ran into an issue making the image_venn.html parent here, in an old version of the code, perform suboptimally when called in an iframe, the fix being …


var vso=null;
try {
if (window.parent) { if (parent.document.URL.indexOf('/image_venn.htm') != -1) { if (1 == 1) { vso=window.self; } else { vso=window.parent; } } }
} catch(exc) {
vso=null;
}

The “fly in the ointment” with yesterday’s Regional Text Google Chart Geo Charts on AlmaLinux Tutorial, in it’s thinking, was assuming that …

regional ISO-3166 codes

… for most users, was likely to be a known entity. Do you know the regional code for the state/county/territory/district/precinct you live in? Well, as it so happens, we do, but only because of doing all this work, with the help of Wikipedia … yes … AU-NSW … but we didn’t, before all this work.

Even before all this work though, somehow, “around the traps” we’d cottoned onto the fact that …

• (the ISO-3166 country code) “AU” was the code for the country Australia (as much as anything because this website’s domain name is rjmprogramming.com.au)
• and those regional ISO-3166 regional codes all start with the ISO-3166 two character country code
• and we’d already written a Regions via Countries web application
• that can help us out (via PHP) … not this time in an iframe, we’ve decided, because it’s faster … filtering it’s contents via …
• PHP shell_exec call like …
  <?php
  
$ctone=shell_exec('fgrep "a' . strtoupper($entered) . '-" ' . $_SERVER['DOCUMENT_ROOT'] . "/HTMLCSS/regions_via_countries.html");

  ?>
  … where that $entered PHP variable contains an ISO-3166 2 letter country code …
• leaving us with data to link a regional ISO-3166 regional code of the form [ISO-3166TwoLetterCountryCode]-[RegionalCodeSuffix] with a Region Name (which is an added bonus not needed to flesh out our URL construction) …
• used in the URL we use to navigate to our derived Google Chart Geo Chart …
• should the user enter, just, an ISO-3166 2 letter country code

It’s in the “better blurbed” prompt window presented off the dropdown Map Chart option selection this can happen. And we’ve decided a savvy user might want the next country of interest by adjusting that address bar URL to, say, Albania’s …

You might recall from QuickChart Interfacing of GraphViz via PHP on AlmaLinux Tutorial we noted …

… the most work left with this interfacing, in all likelihood, will go to the “missing from the list above” Map Chart, and some Venn Chart user entered parameter logics, where any Map Chart replacement logic will never match the Google means by which region boundaries were defined and, hence, able to be allocated a shaded colour, though we think we’ll be able to show region place name text, in position, moving forward, using Google Chart Geo Chart and/or Map Chart and Wikipedia, thanks.

Well, today is a day heading further down that road, certainly not all the way, but some of the way trying to allow for Regional Map Views, not as well as on the deprecated Google Chart Image Chart Map Charts but using text based Google Chart Geo Charts along with those Wikipedia regional location helping informational webpages. This involved, as a start, allowing for our WordPress Blog 404.php work returning HTML (in an iframe …

But, so far, that Google Chart Geo Chart alternative solution can only be practical when all the regional ISO-3166 regional codes land in the one single country. Some countries, in this sense, work quicker because we have already gathered the Wikipedia geographicals, and part of the ongoing aspects to the project, involve …

• collecting more … and iron out …
• subregion “overmentions” …
• better collection method than the prompt window asking for ISO-3166 region code ways at present

• GraphViz Chart
• Google-O-Meter Chart
• Radar Chart
• Pie Chart

… the most work left with this interfacing, in all likelihood, will go to the “missing from the list above” Map Chart, and some Venn Chart user entered parameter logics, where any Map Chart replacement logic will never match the Google means by which region boundaries were defined and, hence, able to be allocated a shaded colour, though we think we’ll be able to show region place name text, in position, moving forward, using Google Chart Geo Chart and/or Map Chart and Wikipedia, thanks.

So, if this is an HTML web application, why the “PHP” mention in the blog posting title? Well, it is good ol’ WordPress Blog TwentyTen theme’s 404.php that remaps URLs from Google Chart Image Chart friendly ones to QuickChart friendly (so far only “splashpage” wise) ones via PHP code snippets …

In the GraphViz Dot command line world, there are a variety of (what we think of as) “verbs” supplied along with Dot installs for various purposes … think neat -n that helped with the Venn Diagrams of day before yesterday’s … but today we’re back to using “verb dot” again, thanks to QuickChart Graph API, thanks, with …

• GraphViz based …
• Dot based html_table_basis.dot code used for …
• graphs based on HTML table code

… for our “how we got there” html_table_basis.php PHP hosting Dot first go HTML Table web application.

In so doing we were able to test the integrity of yesterday’s GraphViz via PHP on AlmaLinux Require Once Tutorial … spoiler alert … all okay (but we still have to remember to make our crontab arrangements for each new such web application)! And remind ourselves to revisit the excellent QuickChart product, which can help us get over the demise of Google Charts Image Charts … somewhat.

Previous relevant GraphViz via PHP on AlmaLinux Require Once Tutorial is shown below.

What is a near relative to …

• external Javascript talents regarding peer to peer arrangements on the client side of web applications …
• for the PHP server side …

… arrangements? We’d say …

• require .. and/or …
• include

… styles of PHP syntax, as explained below …

The include (or require) statement takes all the text/code/markup that exists in the specified file and copies it into the file that uses the include statement.

Including files is very useful when you want to include the same PHP, HTML, or text on multiple pages of a website.

By peer to peer arrangements, we’re referring to those programming occasions where you’ve written a series of web applications, in today’s case, a series of server side PHP ones, further to the work of yesterday’s GraphViz via PHP on AlmaLinux Dot Circular Layout Tutorial, and want each to have means by which they can link to the others. In external Javascript client side land, that would involve an arrangement like …

• visit each HTML code and add the link to the external Javascript … and …
• within that external Javascript a dropdown (or some other HTML) element would be dynamically added to the webpage via DOM methodologies … based on …
• essentially a hardcoded list (which, likely, needs to be rewritten when something new in the peer list happens) the programmer knows about

But using PHP require_once in our minimally tweaked code … just adding …

<?php

require_once(rtrim(dirname(__FILE__), DIRECTORY_SEPARATOR) . DIRECTORY_SEPARATOR . 'make_graphviz_peers.php');

?>

… into twopi_vs_circo_example.php PHP hosting Dot second go Circular Layout web application, is all the “code visiting” needed (as long as somebody … anybody … executes it once in a while … more on that later) in this server side methodology. The reason server side works so well is that server side can read and adjust web server code files, where PHP writes PHP here in this solution, whereas external Javascript client side approaches cannot do this.

With this in mind, what goes into that make_graphviz_peers.php to suit any/all …

• PHP include or require
• standalone web surfing
• curl
• command line
• curl scheduled in crontab
• command line scheduled in crontab

… modes of use to achieve this peer to peer additional dropdown functionality? Quite short …

Previous relevant GraphViz via PHP on AlmaLinux Dot Venn Diagram Box Tutorial is shown below.

Onto yesterday’s GraphViz via PHP on AlmaLinux Dot Venn Diagram Editing Functionality Tutorial the improvements, today, are …

• user can control the Venn (or, it’s getting towards other uses) Diagram fill colour and opacity …
• circles can be ellipses also …
• the dot (or neat -n) shape option Box is coded for as far as diagram editing is concerned … which means some other Polygon shapes work too, except that changes (via two discrete click/taps) followed through on, turns Polygons without 4 sides into a Box with 4 sides
• user can add dot (or neat -n) generic node attributes via the Font Size textbox ( eg. 14 fontcolor=blue margin=0 )

And not that it makes much difference, but dot (or neat -n) graph, or digraph, are both available as graph types for the user to choose from.

Previous relevant GraphViz via PHP on AlmaLinux Dot Venn Diagram Editing Functionality Tutorial is shown below.

Yes, further to yesterday’s GraphViz via PHP on AlmaLinux Dot Venn Diagram Editing Design Tutorial we have some SVG data based Venn Diagram editing functionality to offer the user today. In amongst “editing” is new functionality (via a “+” prefix to the Javascript prompt window answer a user gives) to be able to create new circles or text in SVG and Dot formats. As alluded to yesterday, these Javascript onmousedown and ontouchdown event instigated functions look like …

And along the way, here, we determined by starting down that road, that the effort was not worth the reward to also allow HTML output format also work this Venn Diagram editing functionality. No problems, because in any case, the PNG and JPEG formats are not capable either. It is a case of “horses for courses”!

Similarly for the shape dropdown we’ve opened up again. Only the shape=circle scenario works SVG format output for Venn Diagram editing functionality.

… ideas (turned into a day’s worth of reality), as day two’s job (and hopefully not into day three).

Guess today’s work can be thought of as “a unit’s day”. When you talk of co-ordinates, it’s all relative, right?! With this work, for the first time we can remember, “real world” units such as “inches” (as well as “points” and the pixel “px” webpage units yours truly is most familiar with) make an appearance, of some importance. We’re not going to delve into why dot“neato -n” refers to “inches”, but learn a bit trying to fit in with dot“neato -n”^‘s wooooooorrrrrrrllllllddddd. Our research and development here led to this link for px to inches thoughts, thanks, and this link for px to points thoughts, thanks. We suspect we might need to reference some/all of the three co-ordinate system ideas tomorrow, including the way in Javascript client land Y co-ordinates start at the top with zero and go down the webpage with ever increasing Y’s, but in dot“neato -n” land the Y co-ordinate increases as you go up the webpage, as most good graph systems we’ve ever known, would do, too!

So far with our GraphViz usages, there have been no images, within any SVG output created. Today, at least with the Family Tree functionality, we want to allow image URL user entered imagery to overlay SVG node elements, using that node’s positioning to guide where this overlayed image should be placed, further to yesterday’s Python GraphViz via PHP on AlmaLinux Family Tree Tutorial.

Is it Javascript DOM helping with this? Yes, we host SVG GraphViz output within HTML iframe elements, where (in the spirit of “Client Pre-Emptive Iframe” thinking), which have an onload event Javascript function looking like …

Previous relevant Python GraphViz via PHP on AlmaLinux Organization Hierarchy Emoji Tutorial is shown below.

As far as the title of today’s tutorial goes, onto yesterday’s Python GraphViz via PHP on AlmaLinux Organization Hierarchy Tutorial, we figure “the new word” in the title could have come from …

• Emoji … as we decided upon (as much as anything, because non-ascii characters for other non-English language requirements, might now be possible within the content of the GraphViz entity, as a result) … or …
• Format … or …
• Sharing … or …
• Encoding … or …
• Delimitation

We wanted to look back at yesterday to it’s “code architecture”, if you will, as a “lead in” to where we are coming at here. Yesterday, in the user definable textarea elements …

| … “edge” linkage record set delimiter
; … parent from rest delimiter
, … rest child name(s) delimiter

… this user usage delimiter characters “inhouse rules” architecture contributes to making it all the more crucial in the coding, to nail down how the + character is handled …

… which, as you can see with our HTML form onsubmit event fired Javascript function above, amounts to mapping real content + characters to horizontal tab to differentiate this mode of use from the use HTML form encoding uses for it to represent an encoded space character.

What about if any “edge” names contain one of those delimiters, as above? Well, we try …

… in that regard, and “double decode” (with a bit of nuance in between) on the other side, to try to account for this. We’ll see!

But the day started thinking about Emojis. What would happen in our PDF default output with Emoji content being introduced by the user within input textarea elements, as they go to Draw their Hierarchical Organization chart? Well, not so good. But, thanks to Graphviz not supporting UTF-8 encoding webpage, we got put onto the idea that an alternative, and now the default, format of output could be SVG … and trying it worked … thanks!

And then there’s Sharing (and collaboration) thoughts, again?! Email and SMS hashtagged URLs, again?! Well, here, we modelled ideas from the sharing ideas of the PDF to Images and Microsoft Office on AlmaLinux Tutorial thread of blog postings, ending up with …

And then it occurred to us that there is also the GraphViz graph mode ( default Digraph versus Graph ), and it’s “edge” element background colour and shape and font size, as well as a resizing mechanism, that could be up for grabs, via user input in the tweaked hierarchy_organization.php Hierarchy Organization diagram “drawer”.

Did you guess, regarding the Python Graphviz via PHP work of yesterday’s Python GraphViz via PHP on AlmaLinux Tutorial, we were experiencing File Permission issues?

Well, yesterday, regarding the Python Graphviz via PHP work of yesterday’s Python GraphViz via PHP on AlmaLinux Tutorial, we were experiencing File Permission issues.

We thought we’d move the Python, via PHP processing, totally into the purview of the web server administration owner, by involving a …

1. Korn Shell *.ksh … supervised by …
2. crontab … pointing to …
   
ksh -c 'for i in `find /home/rjmprogr/public_html/ -name "subgraph_example_*.ksh"`; do ksh -c `echo $i`; done'

   … very regularly

… arrangement, but even that failed, in a first incarnation using /tmp/ placement of the Korn Shell file. “Permission denied”, again. Running a Korn Shell from /tmp/ on AlmaLinux must be a no-no, so moved the place to be AlmaLinux web server’s Document Root place, and then things started happening, in the changed subgraph_example.php Python GraphViz using web application.

PHP Image GraphViz via Pear on AlmaLinux Focus Tutorial

It reared it’s ugly head with the Animated GIF Creator here at RJM Programming (helped out by the great Jeroen van Wissen open source work, thanks). And with yesterday’s PHP Image GraphViz via Pear on AlmaLinux Recallable Tutorial it reared up again.

On non-mobile focus goes to the address bar on many web browsers unless there is a (nominally) visible input type=text or textarea next in line.

It’s hard to keep in mind except as it “rears up” in an annoying way, but if we’d thought back, yes, we allow in the linked list feel of revealing textboxes (or textareas) only as they are needed scenarios we allow for two blank ones to be (nominally) visible at any given time … not one … but two, presumably because there is a tiny Javascript DOM “refresh period” not short enough to stop the web browser “desperation measure” (of placing focus in the address bar) happening?!

Why the non-mobile mention? Well, on mobile, a user programming [HTMLelement].focus(); call has no affect, as the touch operating systems need control of focus arrangements, presumably?!

How can we forget? My liege, please accept my humble apologies?!

Why the (nominally) mentions? Well, we have, successfully, in the past, just arranged a (statically HTML placed) textbox (ie. input type=text) that sits outside the viewing screen but not (nominally) invisible (eg. style=’position:absolute;top:-200px;left:-200px;’) can help you avoid the focus going up to the web browser address bar.

So that’s that, and other progress today is to allow the emailing or SMS of a recalled URL Step arrangement via more options on that “Recall Dropdown” we started allowing for yesterday.

Please see this happening in our changed PHP coded My Recipe Steps web application you can also try below.

https://en.wikipedia.org/wiki/Graphviz

The term “GraphViz” …

Graphviz (short for Graph Visualization Software) is a package of open-source tools initiated by AT&T Labs Research for drawing graphs (as in nodes and edges, not as in bar charts) specified in DOT language scripts having the file name extension “gv”. It also provides libraries for software applications to use the tools. Graphviz is free software licensed under the Eclipse Public License.

… we’ve learnt recently, means a lot of things, differently (nuanced) for a range of users, three that we’ve so far become aware of being …

• the recent, alas now deprecated, Google Charts Image Charts GraphViz option means of drawing SVG graphics within an HTML image … we’ve known about before about yesterday …
• today’s interest, that being PHP Image GraphViz via Pear on AlmaLinux install, via the AlmaLinux cPanel “Module Installers” Pear installer page, means by which we can use GraphViz calls in PHP code … and, for the future …
• GraphViz installs for Python via pip

… in amongst many others we’ve seen programmers using … totally cute, totally useful!

It seems with our PHP Image GraphViz via Pear on AlmaLinux as what looks like a very much “pared down” version of the last mode of use above, that we add constructed graph node or edge or cluster objects, and form them into SVG based HTML image elements. It’s look got me thinking “Steps”, then “Recipe Steps”, and back, quietly, to “Any Old Steps” as the day got more generic.

At first we got, as far as Recipes go (and here we thank Italian Wedding Soup for today’s inspiration), to …

• cooking steps showing as Image GraphViz edge graphic components (having arrows connect ellipses containing text, a bit like Speech Bubbles) … and then trying to face the “real world” a user interested in recipes might want to see happen …
• an Image GraphViz node graphic component whose wording could be a user supplied recipe Title along with a “URL” attribute link, optionally user supplied (via our HTML div SVG hosting ondblclick event allowing its contenteditable=true attribute and onblur event means by which these optional additional data items can enter the “mix”, if you’ll pardon the pun), probably pointing back to the original recipe information saucesource … and …
• this title and/or “URL” and/or ingredient list (for example) can all be expressed as the “on hover” title attribute of the tailored user PHP webpage (yes, here we have PHP writing PHP) … and …
• at least on Safari, given a recipe Title defined, we can arrange any browser context menu (ie. right click) over the HTML iframe hosted recipe content “Save Iframe As” option being able to download to a reasonably self explanatory download filename … and/or …
• any web browser’s Add Bookmark functionality can be harnessed to help the user out in such a way that our PHP coded My Recipe Steps web application could end up being your one stop shop “Recipe Organizer” online?!

Google Chart Image Chart Image Map Event Editing Tutorial

If we are talking “layers” (of functionality) again, onto the progress that yesterday’s Google Chart Image Chart Image Map Events Tutorial represented, then , it is logical …

• that if yesterday we presented some programmer defined image map event logic … then, today, we’d want to …
• offer the user the chance to change that default programmer defined image map event logic, to that of their own design

… in the form of

• user defined Javascript .. editable in a …
• HTML textarea element

… and then the coding latching onto a document.createElement(‘script’) paradigm, to add Javascript clientside logic, on the fly.

There’s a first time we can remember aspect to how we present these possibilities to the user. We present it in …

• amongst the inhouse annotation options … as a …
• “reveal” pairing of HTML5 details/summary element combination look … the first time we can remember aspect to that being …
• only initially displaying within the details element innerHTML is a summary element nesting a single “icon like” image (like the other “inhouse annotation” icon images) … but if clicked …
• the details innerHTML has added to it a textarea element …
  
function fillindetsed(odet) {
if (odet.innerHTML.split('</summary>')[1] == '') {
document.getElementById('tdleft').style.verticalAlign='top';
var onls=thescript.split('<scr' + 'ipt type="text/javascript">');
var onlstuff=onls[1].split('</sc' + 'ript>')[0];
odet.innerHTML+='<scr' + 'ipt type="text/javascript">' + "<br><textarea onblur=tproc(this); id=tscript rows=100 cols=80 value=''>" + onlstuff + "</textarea><br></script>";
//odet.innerHTML+='<scr' + 'ipt type="text/javascript">' + "<br><textarea onblur=tproc(this); id=tscript rows=100 cols=80 value=''>" + encodeURIComponent(onlstuff) + "</textarea><br></script>";
//document.getElementById('tscript').value=decodeURIComponent(document.getElementById('tscript').innerHTML);
}
}


… from which document.createElement(‘script’) code onblur event logic emanates …


function tproc(ota) {
//alert(ota.value);
var tag = document.createElement('script');
if (1 == 1) {
obsuffix='&thescript=' + encodeURIComponent(ota.value);
if (document.getElementById('aemail')) {

Google Chart Image Chart Image Map Events Tutorial

We really like HTML image maps, and it occurred to us with yesterday’s Google Chart Image Chart Image Map Tutorial we were hiding its light under some bushel somewhere, because …

• yesterday we introduced with only the onclick event coded for in the HTML area subelements to the map parent element … linked to an …
• associated img element … via an …
• attribute called usemap … and two aspects, at the very least, to stuff under the bushel are …
  1. many more events than onclick can be defined as you define the area subelements … and here’s the kicker …
  2. you can add area subelement event logic that, on paper, would cause interference with other event logic (ie. the same event type in an event bubbling through scenario) but it won’t if you, as a programmer, turn that use of the usemap attribute on and off like a tap

… which, to our mind, represents the bee’s knees of event management. So useful!

To tip our toes into this woooorrrrrlllllddd we’ll show you some newly added area subelement event logics in a Google Chart Image Chart Radar Chart example below …


<map name="mymap" id="mymap"><area onmousedown="defclick(event);" ondblclick="defclick(event);" oncontextmenu="defclick(event);" ontouchend="defclick(event);" ontouchstart="defclick(event);" onmouseout="defclick(event);" onmousemove="defclick(event);" ontouchdown="defclick(event);" onmouseover="defclick(event);" shape="rect" coords="151,34,157,42" id="axis0_0" name="axis0_0" alt="axis0_0" onclick="youralert(this,'This feature name is axis0_0');" nohref=""><area onmousedown="defclick(event);" ondblclick="defclick(event);" oncontextmenu="defclick(event);" ontouchend="defclick(event);" ontouchstart="defclick(event);" onmouseout="defclick(event);" onmousemove="defclick(event);" ontouchdown="defclick(event);" onmouseover="defclick(event);" shape="rect" coords="281,110,288,118" id="axis0_1" name="axis0_1" alt="axis0_1" onclick="youralert(this,'This feature name is axis0_1');" nohref=""><area onmousedown="defclick(event);" ondblclick="defclick(event);" oncontextmenu="defclick(event);" ontouchend="defclick(event);" ontouchstart="defclick(event);" onmouseout="defclick(event);" onmousemove="defclick(event);" ontouchdown="defclick(event);" onmouseover="defclick(event);" shape="rect" coords="281,260,288,268" id="axis0_2" name="axis0_2" alt="axis0_2" onclick="youralert(this,'This feature name is axis0_2');" nohref=""><area onmousedown="defclick(event);" ondblclick="defclick(event);" oncontextmenu="defclick(event);" ontouchend="defclick(event);" ontouchstart="defclick(event);" onmouseout="defclick(event);" onmousemove="defclick(event);" ontouchdown="defclick(event);" onmouseover="defclick(event);" shape="rect" coords="151,336,157,344" id="axis0_3" name="axis0_3" alt="axis0_3" onclick="youralert(this,'This feature name is axis0_3');" nohref=""><area onmousedown="defclick(event);" ondblclick="defclick(event);" oncontextmenu="defclick(event);" ontouchend="defclick(event);" ontouchstart="defclick(event);" onmouseout="defclick(event);" onmousemove="defclick(event);" ontouchdown="defclick(event);" onmouseover="defclick(event);" shape="rect" coords="20,260,27,268" id="axis0_4" name="axis0_4" alt="axis0_4" onclick="youralert(this,'This feature name is axis0_4');" nohref=""><area onmousedown="defclick(event);" ondblclick="defclick(event);" oncontextmenu="defclick(event);" ontouchend="defclick(event);" ontouchstart="defclick(event);" onmouseout="defclick(event);" onmousemove="defclick(event);" ontouchdown="defclick(event);" onmouseover="defclick(event);" shape="rect" coords="20,110,27,118" id="axis0_5" name="axis0_5" alt="axis0_5" onclick="youralert(this,'This feature name is axis0_5');" nohref=""><area id="adef" onclick=" defclick(event); if (!done) { done=false; if (atstart) { normalcall=false; ask(null); normalcall=true; atstart=false; } else { ask(event); } } " shape="default" nohref=""></map>


… with new relevant event code snippet to help add intelligence to the event logic of our Google Chart Image Chart interfacing web application …


function defclick(evt) {
switch ('' + evt.type) {
case 'click':
alert('Welcome to RJM Programming interfacing to Google Charts Image Chart ' + cname);
break;

default:
switch (('' + evt.type + ' ').substring(0,5)) {
case 'mouse':
document.getElementById('myh3').innerHTML='RJM Programming - November, 2023 ... non-mobile mouse event ' + evt.type + ' called by ' + ('' + evt.target.id);
break;

case 'touch':
document.getElementById('myh3').innerHTML='RJM Programming - November, 2023 ... mobile touch event ' + evt.type + ' called by ' + ('' + evt.target.id);
break;

default:
alert(evt.type);
break;

}

Do you like to come at explaining things in layers? Sort of like the analogy …

• you start a project thinking of it in terms of “2D” … and then to move forward …
• you spend a day making it work for “3D” (and keep the “2D” working as well)

… or …

• you start a web application project thinking of only working via a URL entered on the web browser address bar … and then to move forward …
• you spend a day making it work for serving the same purpose and/or a difference purpose called within an HTML iframe (and keep it working for the address bar way as well)

And so we look at a “picturesque” but “kinda dumb” (as far as “action items” go) image we have coming off the interfacing to Google Charts Image Chart. Where can we go here? Well, it would be kind of you to take it to the beach, but that’s not always a possibility now, is it?! Were you pulling my leg?! Tee hee. No, we were thinking … oh no … we have a bad feeling about this … let’s open it up to the class … anyone, anyone? Yes, Louis, would you and Auguste like to share with the class what is so amusing to you?

Okay, thank you for your thoughts on this, and yes, you could take the “picture” to “a picture show”. Yes, very droll, indeed. Any other ideas? Okay, Johann, you say the idea just “clicked” with you. This sounds promising. Go on …

Indeed, a young “picturesque” might like to go tap dancing, that is true. Sheeeeesh! But given the lesson is a Computing one, rather than Drama or Dance or Music or the Arts, maybe we would be looking for a way to use the picture in an enhanced way. Okay Kevin, we’ll try you. What do you think?

Previous relevant Google Chart Image Chart Dynamic Icons Tutorial is shown below.

Does statistics have to be staid and boring? Kitch and quiche?! Welcome to the wooorrrlllddd of Google Charts Image Chart Dynamic Icons!

Think of Dynamic Icons as a way to decorate one or more data points displayed in one of …

• Line Chart
• Bar Chart
• Map Chart
• Radar Chart

We had that certain “Wow^!“ factor going as we remembered our state’s motto from some years back, and we tried out the Map Chart to see whether we could embellish the map with a Dynamic Icon relevant to New South Wales, as you can see with today’s tutorial picture.

We’ll show you the most recent snapshot of Javascript parameters a little later, but the change for this is an optional one up to the user to work out, with prompts such as the Map Chart one updated …

Enter vertical bar separated country ISO Country and/or Region Code list. Please note that optional Dynamic Icons are available via a suffixing string example applied to the second data point such as &chem=y;s=bubble_icon_text_small;d=ski,bb,NSW%20State%20of%20Wow!,FFFFFF;dp=1;ds=0 eg. AU-NT|AU-NSW|AU-SA|NZ|IN’

… even though it is only visual by nature, presented as an update image still presented and updated periodically. Go figure?!

… and offer a way to help the “Broadcast Talk” demonstrator “speak” during their demonstration, effectively. In so doing, we are going to add to …

• the demonstrator’s visual inputs coming from that canvas annotator helper … with, today …
• the demonstrator’s commentary, collected via an HTML textarea element (to optionally supplement the visuals) from that canvas annotator helper’s originator window (ie. the Google Charts Image Chart interfacing supervisor) … presented …

… via a new “middle of three slide” …

Previous relevant Google Chart Image Chart Radar Chart Tutorial is shown below.

Onto yesterday’s Google Chart Image Chart Box Chart Tutorial, today we have a two part stepping forward via new …

• Radar Chart interfacing for Google Charts Image Chart … and …
• first tentative steps towards, on non-mobile platforms, allowing for text placement rubber banding

Why the trepidation? Well, so far, when the text is angled we can’t understand what results we are getting back from a call to [element].getBoundingClientRect() just yet.

Why is this needed? Again, with the questions! Well, Mr De Niro, you see, well, somebody might want to go onto that more complex annotating.

And why would they do that? Sheesh. Well, Mr De Niro, sir, you see, sometimes things happen in life, and well, fingers slip on keyboards, and mice get awfullllly nervous around screens these days.

Yeh, well, show us the money, wiseguy. Who’s is that question? And what’s with the questions? Well, you see, Mr De Niro, the money is if we can get PHP text placement for text at an angle, where it rotates from the middle of the text, to get a similar positioning to good ol’ … pardon, Mr De Niro … good and well respected Javascript transform rotations … not with a triple pike, Mr De Niro, but you’re awfulllllly close, Mr De Niro, sir … rather, we throw in a couple of translations … no, not Latin, Mr De Niro … of co-ordinates, Mr De Niro.

And that will bring in how much by next Tuesday? Back to the questions? Why so many questions? We think it’s a pretty big money spinner, Mr De Niro, sir, and we think you should come back next Tuesday, and we can show you the ropes. Sweat, oozing from the brow, as Mr De Niro exits stage left.

And just while we have a few minutes, here’s the updated Javascript parameterization …

… that goes into helping make the changed latest draft image_venn.html Google Chart Image Chart Venn Chart or Scatter Chart or GraphViz Chart or Pie Chart or Line Chart or Bar Chart or Candlestick/Box Chart or Google-O-Meter Chart or Radar Chart or Map Chart interfacing web application you can also try below, have regular sleepovers on cloud nine.

Did you know?

Did you notice the inclusion of CSS styling …

<style>

#fsangle { background-image: url("data:image/svg+xml;utf8,<svg xmlns='http://www.w3.org/2000/svg' width='24' height='24' viewport='0 0 100 100' style='font-family:Verdana;font-size:10px;'><text y='50%'> \00B0</text></svg>"); background-repeat: no-repeat; background-position: center right; }

</style>

? It styles an input type=number textbox where a placeholder is not really an option to explain a textbox’s purpose, and we do dislike set aside labels, these days. It’s also a way to explain the textbox for mobile users who do not get a hovering message to help. It’s also got an internationalization feel to it, using the degree sign emoji ° (ie. &#176; or that \u0080 UTF-16 Encoding style of definition suitable for CSS styling usage) to both associate the units we’d want, as well as that we are asking for an angle. Clockwise or anticlockwise, alas, comes down to user experience!

Previous relevant Google Chart Image Chart Colour Tutorial is shown below.

Restricting you creatives to “inhouse annotations” of the “gray variety” might be seen as a bit boooorrrriiiinnnngggg! And so, onto the progress up to yesterday’s Google Chart Image Chart Rubber Banding Tutorial, today we’ve added a …

• colour picker … way user can define an “inhouse annotations” colour … and while we were at it …
• as far as text “inhouse annotations” go we’ve added a counterclockwise from the horizon, in degrees, way to define an angle the text should be placed at … and …
• we’ve stopped closing off the text font size dropdown too early, allowing the user to mix it up with their annotations, and so …
  

  We now recommend, for those users pushing the boundaries of functionality, to gather all their “inhouse annotations” together before any “graphical canvas annotations” are thought about.

Which begs the question …

Where do you get it?

Well, here, via … dare we say it?! … … via …

Mantissa Madness Monday

Both colour and degree counterclockwise angle became “Mantissa Madness Monday” tragics, a bit like moi, really?

How did we express these two measures?

• colour can be derived at the 404.php end via mantissae that are 9 or more long where a number of the form rrrgggbbb is numerical and passed across to 404.php in the y co-ordinate mantissa … while … kind of crazily …
• angle can be a set of zeros in the x co-ordinate mantissa represented by zero characters to the length of the angle from 1 to 359 in front of a pre-existant font size (in px) usage, from last “Mantissa Madness Monday” (us getting away with this because no font size should start with a zero)

Oh! We have such fun around here?! Below is PHP WordPress blog 404.php code …

<?php

// text placement
$black = imagecolorallocatealpha($im, 1, 1, 1, 0);

  … at least for us (being as we do not want to clobber any pinch or spread gesture ideas, for the user)
• is only a really, “nice to have” functionality idea

Even so, achieving even a 95% percent working “rubber band” is like … is like …

Barracking for Hairtie United …
You little beauty, Untied!

And so, further to yesterday’s Google Chart Image Chart Circle Annotation Tutorial we have this non-mobile “Rubber Banding” inhouse annotation functionality included in our changed latest draft image_venn.html Google Chart Image Chart Venn Chart or Scatter Chart or GraphViz Chart or Pie Chart or Line Chart or Bar Chart or Candlestick Chart or Map Chart interfacing web application you can also try below.

But there’s more! Despite how long out of the day it takes to barrack for Hairtie United, there was a mobile matter we resolved. A slide in today’s animated GIF presentation shows the issue. On mobile platforms, with these inhouse annotations, it would immediately show a tiny annotation. There panned out to be two event programming related issues we needed to fix related to this problem …

1. change looking for a “touchstart” event, and instead look for a “touchdown” event for a document.body scope (else we might have restricted the “scope” to just document.getEleementById(‘myvenn’) as another approach (and you should note our event.stopPropagation() statements in lots of places as another research point for you)) because we are talking “discrete click” user behaviour we are targeting … as well as …
2. start checking that the co-ordinates calculated fall into the range of the Google Charts Image Chart image dimensions … doh!


document.body.addEventListener('touchdown', function(evt){
//alert(8);
evt = evt || window.event;

evt.preventDefault();

elemLeft = document.getElementById('myvenn').offsetLeft;
elemTop = document.getElementById('myvenn').offsetTop;

//document.getElementById('myh3').innerHTML+=' ' + elemLeft + ';' + elemTop;

if (evt.touches) {
if (evt.touches[0].pageX) {
//alert('here');
x = evt.touches[0].pageX + document.body.scrollLeft - elemLeft;
y = evt.touches[0].pageY + document.body.scrollTop - elemTop;
if (x >= 0 && x <= eval(('' + document.getElementById('myvenn').width).replace('px','')) && y >= 0 && y <= eval(('' + document.getElementById('myvenn').height).replace('px',''))) {
if (curno >= 0 && (lastx != x || lasty != y)) {
xneeds.push(x);
yneeds.push(y);
checkforaction(false,-1,-1);
}
lastx=x;
lasty=y;
}
//alert('x:' + x + ' and y:' + y);
} else {
//alert('Here');
x = evt.touches[0].clientX + document.body.scrollLeft - elemLeft;
y = evt.touches[0].clientY + document.body.scrollTop - elemTop;

Did you know?

Well … we didn’t?! We happened to try the web application above on a tiny iPad and saw that HTML button elements with an innerHTML label containing a line feed ( ie. <br> ) only showed the top line, and, alas, for that button in question, the vital new information used to be on the second line. Hence our fix …


//document.getElementById('bshare').innerHTML='Repainting Top Left Image Periodically ... <br>Click here to Broadcast this session to other interested parties ...';
document.getElementById('bshare').innerHTML='Click here to Broadcast this session to other interested parties ...<br>Repainting Top Left Image Periodically ...';

The CSS border-radius property has come to the rescue of many a programmer, saving us from resorting to SVG to display circle or ellipses or arcs of various sorts …

• Broadcast … their work as it happens, dynamically …
• to an emailee list audience

… and we’re calling this …

Broadcast Talk

… even though it is only visual by nature, presented as an update image still presented and updated periodically. Go figure?! We’re blaming that supper time two back. We’re not sure?!

Anyway, we hope you try out the new arrangements in our changed seventh draft image_venn.html Google Chart Image Chart Venn Chart or Scatter Chart or GraphViz Chart or Pie Chart or Line Chart or Bar Chart or Candlestick Chart or Map Chart interfacing web application you can also try below, and helped out by a WordPress blog good ol’ TwentyTen theme 404.php which now includes …

<?php

if (isset($_POST['canvcont']) && isset($_POST['uniquifier']) && strpos(('?' . $_SERVER['QUERY_STRING']), 'cht=') === false) {
if (isset($_POST['uniquifier'])) {
$uniquifier=str_replace('+',' ',urldecode($_POST['uniquifier']));
}
if ($uniquifier == '') {
$uniquifier='_' . rand(0,78654356);
file_put_contents($_SERVER['DOCUMENT_ROOT'] . DIRECTORY_SEPARATOR . "presentation" . $uniquifier . ".png", base64_decode( explode('base64,', str_replace(' ','+',urldecode($_POST['canvcont'])))[1]));
echo "<html><body onload=\"if (parent.document.getElementById('uniquifier')) { if (parent.document.getElementById('uniquifier').value == '') { parent.document.getElementById('uniquifier').value='" . $uniquifier . "'; } }\"></body></html>";

}

… featuring our first use of this 404.php in response to a method=POST form call. Verrrrrryyyy interesting!

Previous relevant Google Chart Image Chart Statistical Charts Tutorial is shown below.

Further to yesterday’s Google Chart Image Chart Pie Chart Tutorial, today, we embark on our first ventures into composite charts, along what we like to think of as “statistical lines”, regarding interfacing to Google Charts Image Chart …

• Line Chart … with its three display options …
  1. Even
  2. Sparkline
  3. Just XY
• Bar Chart … with its three display options …
  1. Grouped
  2. Stacked
  3. Overlapped
• Candlestick Chart

… the latter being like a “parasite” display idea off the more conventional Statistical Graph favourites, the Line Chart and Bar Chart, where you have a relationship between a numerical concept (eg. sales) and another type of concept (eg. month of the year), and you want to present the data in a graphical form.

Again, we haven’t stopped our “retweaking”. We might “retweak” in the morning or we might “retweak” over a coffee break or we might “retweak” at supper time, but the end result is, well, you’re reading it now!

Previous relevant Google Chart Image Chart Pie Chart Tutorial is shown below.

As we intimated in yesterday’s Google Chart Image Chart GraphViz Chart Tutorial …

start with an at least two part “inhouse phase” of additional “extra to text” annotation functionality possibilities …

… we would return! And so, here thou lingers. It’s “part two” day, even bigger than “Ben Hur” in certain outback towns we’re a little bit shy to divulge until we get to know our readers that little bit better.

Yes, we are dovetailing with work we’ve done in the past using the excellent …

• canvas … element introduced with HTML5 … whereby …
• annotations like …
  1. scribble … as the default, and various other …
  2. discrete click shapes … and …
  3. text … including emojis … and …
  4. image

  … annotating modus operandi

… can be part of the arrangements. It works that the Annotation Helper is opened …

• in a new “known about” popup window … looking out for …
• parent based “img” element (in the modus operandi we use, calling it, regarding the parent top left image) … so as to be able to …
• populate its canvas element with a clone of that calling “img” graphical content … but add into the mix …
• menu driven annotation functionality which can change that canvas look and underlying data … and …
• the caller can keep track of this and arrange, or not, for these changes to be reflected back at its top left “img” element … the catch being …
• the “within range of GET argument” limits are ruined by this introduction of graphical data, and so in agreeing to this, a user forgoes those simpler sharing and annotating functionalities of yesterday’s (and before) work … though your normal image sharing capabilities via the web browser remain in the caller and the called

As well, today, we are introducing new Google Charts Image Chart Pie Chart interfacing, and because this chart type can have the three …

• Normal
• 3D
• Concentric

… guises, there was some work to keep us off this street (okay … so we divulged … again) …

Today we have two strands of forward progress, onto the progress up to yesterday’s Google Chart Image Chart Scatter Chart Tutorial, they being …

• establish a new interfacing to GraphViz Chart …
  

  GraphViz is a package of open source tools for visualizing connectivity graphs. You can create GraphViz graphs using the DOT language and your choice of layout engines.

  … a chart looking a bit like Organization Charts …

  Org charts are diagrams of a hierarchy of nodes, commonly used to portray superior/subordinate relationships in an organization. A family tree is a type of org chart.

  
  

• start with an at least two part “inhouse phase” of additional “extra to text” annotation functionality possibilities … just starting with …
  1. line
  2. open rectangle
  3. filled rectangle

… additional functionality, that we may well add to, but being as we feel a change we’ll leave that for another time.

Did you know?

Would you believe, at least to us, it is far less obvious how to display a straight line (that is perhaps not horizontal nor vertical) within a webpage, than it is to display a rectangle, filled or not?! Talk about irony! Over time, we have developed …

• HTML hr elements (with a rotation) … and the less kludgy …
• HTML div (defining a box with defined dimensions) for a nested SVG element containing the line definition using percentage dimensions

… in the past, for when we needed to do this. But, today, we’d like to thank this great webpage for its suggestion to involve linear gradients …


<style>

.crossedtotl {
background:
linear-gradient(to top left,
rgba(0,0,0,0) 0%,
rgba(0,0,0,0) calc(50% - 0.8px),
rgba(0,0,0,1) 50%,
rgba(0,0,0,0) calc(50% + 0.8px),
rgba(0,0,0,0) 100%);
}
.crossedtotr {
background:
linear-gradient(to top right,
rgba(0,0,0,0) 0%,
rgba(0,0,0,0) calc(50% - 0.8px),
rgba(0,0,0,1) 50%,
rgba(0,0,0,0) calc(50% + 0.8px),

… in a, basically, CSS solution. Great stuff, thanks!

Did you know?

In this online world with so many platforms and devices and software choices, there is no need to ever be embarrassed by what might seem an obvious feature you’ve missed.

Take the way on macOS, but not iOS, using a web browser to get to YouTube, you can flag that a video should loop. Especially good for …

• song obsessions …
• earworms you need to salve

… and what about if your shower is taking an awfully long time?! Please be careful with moisture and devices, though, in the bathroom!

How does it happen? Right click the play button, and looping is there as the top option. Now back to that shower song obsession.

Did you know?

As far as this WordPress blog’s 404.php role goes in all this, we were keen to maintain Venn Diagrams that were purely image based data, because the web browser sharing mechanisms are so much better this way, else we were tempted to just construct a webpage HTML dataset positioning text in an absolute way with a Venn Chart background image. In order to do these purely image based Venn Diagrams we used PHP’s GD image library as per …

<?php

if (strpos(('?' . $_SERVER['QUERY_STRING']), '?cht=') !== false || strpos(('?' . $_SERVER['QUERY_STRING']), '&cht=') !== false) {

$theqs=str_replace('??','?',('?' . $_SERVER['QUERY_STRING']));
if (strpos($theqs, '?chs=') === false && strpos($theqs, '&chs=') === false) {
$theqs='?chs=' . $newWidth . 'x' . $newHeight . '&' . explode('?', $theqs)[1];
}

if (strpos(('?' . $_SERVER['QUERY_STRING']), 'text1=') !== false) {
$theone=2;
$im = imagecreatefromstring(file_get_contents('http://chart.googleapis.com/chart' . explode('&text1=', $theqs)[0]));

if (7 == 7) {

$plotstring=str_replace('+',' ',urldecode($_GET['text1']));
$csv=explode(',', $plotstring);
$black = imagecolorallocatealpha($im, 1, 1, 1, 0);
if (sizeof($csv) >= 3) {
try {
if (function_exists('imagettftext')) {
if (explode('' . $csv[0] . ',' . $csv[1] . ',', $plotstring)[1] !== '') {
//echo explode('' . $csv[0] . ',' . $csv[1] . ',', $plotstring)[1];
//exit;
imagettftext($im, 10, 0, $csv[0], $csv[1], $black, realpath('arial.ttf'), explode('' . $csv[0] . ',' . $csv[1] . ',', $plotstring)[1]);
}
}
} catch (Exception $e) { }
while (isset($_GET['text' . $theone])) {
$plotstring=str_replace('+',' ',urldecode($_GET['text' . $theone]));
$csv=explode(',', $plotstring);
if (sizeof($csv) >= 3) {
try {
if (function_exists('imagettftext')) {
if (explode('' . $csv[0] . ',' . $csv[1] . ',', $plotstring)[1] !== '') {
imagettftext($im, 10, 0, $csv[0], $csv[1], $black, realpath('arial.ttf'), explode('' . $csv[0] . ',' . $csv[1] . ',', $plotstring)[1]);
}
}
} catch (Exception $e) { }
}
$theone++;
}
}

}

imagepng($im);
imagedestroy($im);

Previous relevant Google Chart Image Chart Venn Chart Interfacing Primer Tutorial is shown below.

So, moving on from Google Charts Image Chart Map Charts, today, let’s turn our attention to Google Charts Image Chart Venn Charts which we were dead set curious about given work we’d done in the past regarding Venn Diagrams, which we referenced when we presented Flowchart and Venn Diagram and Mind Map Token Subject Emoji Tutorial some time back. Gobsmackingly good is the Google approach, again, as you’d expect, but the approach covers different ground, so one feels one should go back to Primary School! You thought we were going to give away the answer to one of those security questions, didn’t you?! Didn’t you!?! Well, the answer is “Gryffindor Slytherin Ravenclaw Hufflepuff Junior Business College” … if you must know.

The sharing capabilities are good with the Google Charts approach too, given we are creating an HTML image, as our WordPress blog good ol’ 404.php has been woken up to address via …

<?php

if (strpos(('?' . $_SERVER['QUERY_STRING']), '?cht=') !== false || strpos(('?' . $_SERVER['QUERY_STRING']), '&cht=') !== false) {

$theqs=str_replace('??','?',('?' . $_SERVER['QUERY_STRING']));
if (strpos($theqs, '?chs=') === false && strpos($theqs, '&chs=') === false) {
$theqs='?chs=' . $newWidth . 'x' . $newHeight . '&' . explode('?', $theqs)[1];
}


header('Content-Type: image/png');
echo file_get_contents('http://chart.googleapis.com/chart' . $theqs);
exit;

}

?>

Yes, all these Image Chart smarts come, essentially, from a “one line” calling URL! Who’d have believed it! Shiver me timbers!

Well, it’s early days with this Venn Chart interfacing where we allow for …

• circle (think up to three) definition … and the rest, in this first draft (hoping you’ve done some reading) …
• legend and title and colour selection user definitions dumped into a fairly unfriendly “the rest” Javascript prompt entry we ask of the user should they go ahead with the previous definition … and …
• sharing and collaboration email and SMS functionality

… we hope you try via our “proof of concept” first draft image_venn.html Google Chart Image Chart Venn Chart interfacing web application you can also try below …
