Python GraphViz via PHP on AlmaLinux Organization Hierarchy Emoji Tutorial

Python GraphViz via PHP on AlmaLinux Organization Hierarchy Emoji Tutorial   ๐Ÿ”

As far as the title of todayโ€™s tutorial goes, onto yesterdayโ€™s Python GraphViz via PHP on AlmaLinux Organization Hierarchy Tutorial, we figure โ€œthe new wordโ€ in the title could have come from โ€ฆ

  • Emoji โ€ฆ 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) โ€ฆ or โ€ฆ
  • Format โ€ฆ or โ€ฆ
  • Sharing โ€ฆ or โ€ฆ
  • Encoding โ€ฆ or โ€ฆ
  • Delimitation

We wanted to look back at yesterday to itโ€™s โ€œcode architectureโ€, if you will, as a โ€œlead inโ€ to where we are coming at here. Yesterday, in the user definable textarea elements โ€ฆ

| โ€ฆ โ€œedgeโ€ linkage record set delimiter
; โ€ฆ parent from rest delimiter
, โ€ฆ rest child name(s) delimiter

โ€ฆ this user usage delimiter characters โ€œinhouse rulesโ€ architecture contributes to making it all the more crucial in the coding, to nail down how the + character is handled โ€ฆ

<?php echo โ€

function contentfix(inid) {
document.getElementById('ititle').value=document.getElementById('ititle').value.replace(/\+/g,'-').replace(/\=/g,'-').replace(/\ /g,'-');
document.getElementById('none').value=various(document.getElementById('one').value.replace(/\+/g,String.fromCharCode(9)));
document.getElementById('ntwo').value=various(document.getElementById('two').value.replace(/\+/g,String.fromCharCode(9)));
document.getElementById('nthree').value=various(document.getElementById('three').value.replace(/\+/g,String.fromCharCode(9)));
return inid;
}

โ€œ; ?>

โ€ฆ 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. Are you now getting a bit of an idea with todayโ€™s โ€œtidying upโ€ and โ€œnuancingโ€ feel?!

What about if any โ€œedgeโ€ names contain one of those delimiters, as above? Well, we try โ€ฆ

<?php echo โ€

function various(indi) {
var outdi=indi;
outdi=outdi.replace(/\|\;/g, encodeURIComponent('|') + ';');
outdi=outdi.replace(/\,\;/g, encodeURIComponent(',') + ';');
outdi=outdi.replace(/\;\;/g, encodeURIComponent(';') + ';');

outdi=outdi.replace(/\|\,/g, encodeURIComponent('|') + ',');
outdi=outdi.replace(/\,\,/g, encodeURIComponent(',') + ',');
outdi=outdi.replace(/\;\,/g, encodeURIComponent(';') + ',');

outdi=outdi.replace(/\|\|/g, encodeURIComponent('|') + '|');
outdi=outdi.replace(/\,\|/g, encodeURIComponent(',') + '|');
outdi=outdi.replace(/\;\|/g, encodeURIComponent(';') + '|');

return outdi;
}

โ€œ; ?>

โ€ฆ in that regard, and โ€œdouble decodeโ€ (with a bit of nuance in between) on the other side, to try to account for this. Weโ€™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 โ€ฆ and trying it worked โ€ฆ thanks!

And then thereโ€™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 โ€ฆ

<?php echo โ€

event.stopPropagation();

if (em == null) { em=''; }

document.getElementById('ntwo').value=various(document.getElementById('two').value.replace(/\+/g,String.fromCharCode(9)));

document.getElementById('dimap').innerHTML=\"<a style=display:none; id=theaemail target=_blank href='mailto:\" + em + \"'>Email</a>\";
document.getElementById('theaemail').click();
}
return false;
}

Stop Press

And then it occurred to us that there is also the GraphViz graph mode ( default Digraph versus Graph ), and itโ€™s โ€œedgeโ€ element background colour and shape and font size, as well as a resizing mechanism, that could be up for grabs, via user input in thetweaked hierarchy_organizationโšซphp Hierarchy Organization diagram โ€œdrawerโ€.

Calling cab (6754 โ€“ 6756 + 4).

Huh?!

Calling the second cab off the rank.

Yes, now that we understand a bit more about file permission issues, after yesterdayโ€™s Python GraphViz via PHP on AlmaLinux Permissions Tutorial, having PHP hosting Python with GraphViz calls, letโ€™s turn our attention to the issue of โ€œlots of dataโ€, today, with our โ€ฆ


Organization Hierarchyist

โ€ฆ what do you say?! Itโ€™s a bit embarrassingly easy a remedy because we are writing in PHP, to just โ€ฆ

  • make any $_GET[] (web browser address bar arguments) references become $_POST[] equivalents โ€ฆ and any โ€ฆ
  • HTML form method=GET should become HTML form method=POST

Calling log (6754 โ€“ 6756 + 4 โ€“ 1) โ€ฆ to fall off.

Python code wise, our hierarchy_organizationโšซpy inspiration came from https://graphviz.readthedocs.io/en/stable/examples.html thanks.

Then we worked on PHP hierarchy_organizationโšซphp to be as close to being a buddy with a Python as, well, Monty?!

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

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

We thought weโ€™d move the Python, via PHP processing, totally into the purview of the web server administration owner, by involving a โ€ฆ

  1. Korn Shell *.ksh โ€ฆ supervised by โ€ฆ
  2. crontab โ€ฆ pointing to โ€ฆ

    ksh -c 'for i in `find /home/rjmprogr/public_html/ -name "subgraph_example_*.ksh"`; do ksh -c `echo $i`; done'

    โ€ฆ very regularly

โ€ฆ arrangement, but even that failed, in a first incarnation using /tmp/ placement of the Korn Shell file. โ€œPermission deniedโ€, again. Running a Korn Shell from /tmp/ on AlmaLinux must be a no-no, so moved the place to be AlmaLinux web serverโ€™s Document Root place, and then things started happening, in thechanged subgraph_exampleโšซphp Python GraphViz using web application.

Do you remember reading, with PHP Image GraphViz via Pear on AlmaLinux Primer Tutorial below, our outlining three known GraphViz guises โ€ฆ

  • the recent, alas now deprecated, Google Charts Image Charts GraphViz option means of drawing SVG graphics within an HTML image โ€ฆ weโ€™ve known about before about yesterday โ€ฆ
  • todayโ€™s interest, that being PHP Image GraphViz via Pear on AlmaLinux install, via the AlmaLinux cPanel โ€œModule Installersโ€ Pear installer page, means by which we can use GraphViz calls in PHP code โ€ฆ and, for the future โ€ฆ
  • GraphViz installs for Python via pip

โ€ฆ? Well, today, we start down the road of โ€ฆ

  1. installing Python GraphViz package via โ€ฆ

    pip install graphviz

    โ€ฆ then โ€ฆ
  2. getting great help from https://graphviz.readthedocs.io/en/stable/, thanks, as the Python code basis we call subgraph_exampleโšซpy โ€ฆ and โ€ฆ
  3. used and remoulded by our overseeing PHP subgraph_exampleโšซphp Python GraphViz using web application

โ€ฆ we need to work on more after this first draft start to another road of our GraphViz journey last talked about at PHP Image GraphViz via Pear on AlmaLinux Focus Tutorial.

It reared itโ€™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 yesterdayโ€™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.

Itโ€™s hard to keep in mind except as it โ€œrears upโ€ in an annoying way, but if weโ€™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 โ€ฆ not one โ€ฆ but two, presumably because there is a tiny Javascript DOM โ€œrefresh periodโ€ not short enough to stop the web browser โ€œdesperation measureโ€ (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=โ€™position:absolute;top:-200px;left:-200px;โ€™) can help you avoid the focus going up to the web browser address bar.

So thatโ€™s that, and other progress today is to allow the emailing or SMS of a recalled URL Step arrangement via more options on that โ€œRecall Dropdownโ€ we started allowing for yesterday.

Please see this happening in ourchanged PHPโšชcoded My Recipe Steps web application you can also try below.

After yesterdayโ€™s PHP Image GraphViz via Pear on AlmaLinux Sharing Tutorial some readers may be curious to understand the distinction between โ€ฆ

  • email and SMS sharing โ€ฆ and โ€ฆ
  • inhouse intersessional sharing via window.localStorage (ie. like HTTP Cookies)

โ€ฆ over yesterdayโ€™s and todayโ€™s blog posting timings. Simply put, for us, we โ€ฆ

  • take a deep breath before starting intersessional window.localStorage work, as it is not to be sneezed at, as any sort of doddle (at least for us) โ€ฆ as well as โ€ฆ
  • since last intersessional window.localStorage work weโ€™ve started using email and SMS sharing hashtagging arrangements that fit in, like a glove, with this intersessional window.localStorage work โ€ฆ so that โ€ฆ
  • even though, we write the code here in PHP, all this functionality is client based โ€ฆ which we like because โ€ฆ
  • get the idea correct, with careful forward planning and implementation, weโ€™ll be able to apply similar such thinking into the future, whether that be for clientside only web applications and/or ones that call on serverside code (like PHP) โ€ฆ and โ€ฆ
  • if we can keep things just clientside more readers can be involved, we figure

If youโ€™re wondering about the worry of any of this, it is to do with large title and/or URL link and/or ingredient type data whose data length could be huge, where most of our concern lies, and โ€ฆ

  • hashtagging (where data limits are so much longer) can help it remain as a clientside only solution environment (rather than relying on some form method=POST to a serverside (eg. PHP) receiver solution) โ€ฆ
  • window.localStorage is a step up from the HTTP Cookie style of intersessional (personal) storage as far as amounts that can be stored is concerned

What are we aiming for here, then, with our improvements?

  • extend the existant email and SMS functionality โ€ฆ

The term โ€œGraphVizโ€ โ€ฆ

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 โ€œgvโ€. It also provides libraries for software applications to use the tools. Graphviz is free software licensed under the Eclipse Public License.

โ€ฆ weโ€™ve learnt recently, means a lot of things, differently (nuanced) for a range of users, three that weโ€™ve so far become aware of being โ€ฆ

  • the recent, alas now deprecated, Google Charts Image Charts GraphViz option means of drawing SVG graphics within an HTML image โ€ฆ weโ€™ve known about before about yesterday โ€ฆ
  • todayโ€™s interest, that being PHP Image GraphViz via Pear on AlmaLinux install, via the AlmaLinux cPanel โ€œModule Installersโ€ Pear installer page, means by which we can use GraphViz calls in PHP code โ€ฆ and, for the future โ€ฆ
  • GraphViz installs for Python via pip

โ€ฆ in amongst many others weโ€™ve seen programmers using โ€ฆ totally cute, totally useful!

It seems with our PHP Image GraphViz via Pear on AlmaLinux as what looks like a very much โ€œpared downโ€ 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. Itโ€™s look got me thinking โ€œStepsโ€, then โ€œRecipe Stepsโ€, and back, quietly, to โ€œAny Old Stepsโ€ as the day got more generic.

At first we got, as far as Recipes go (and here we thank Italian Wedding Soup for todayโ€™s inspiration), to โ€ฆ

  • cooking steps showing as Image GraphViz edge graphic components (having arrows connect ellipses containing text, a bit like Speech Bubbles) โ€ฆ and then trying to face the โ€œreal worldโ€ a user interested in recipes might want to see happen โ€ฆ
  • an Image GraphViz node graphic component whose wording could be a user supplied recipe Title along with a โ€œURLโ€ 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 โ€œmixโ€, if youโ€™ll pardon the pun), probably pointing back to the original recipe information saucesource โ€ฆ and โ€ฆ
  • this title and/or โ€œURLโ€ and/or ingredient list (for example) can all be expressed as the โ€œon hoverโ€ title attribute of the tailored user PHP webpage (yes, here we have PHP writing PHP) โ€ฆ and โ€ฆ
  • 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 โ€œSave Iframe Asโ€ option being able to download to a reasonably self explanatory download filename โ€ฆ and/or โ€ฆ
  • any web browserโ€™s Add Bookmark functionality can be harnessed to help the user out in such a way that our PHPโšชcoded My Recipe Steps web application could end up being your one stop shop โ€œRecipe Organizerโ€ online?!

Google Chart Image Chart Angled Text Annotation Tutorial   ๐Ÿ”

Itโ€™s Tuesday, in places around the world, looking back at yesterdayโ€™s Google Chart Image Chart Image Map Event Editing Tutorial. Canโ€™t help but think weโ€™ve forgotten something. Ah yes โ€ฆ

You talkinโ€™ to me? You talkinโ€™ to me? Meanwhile, back at the questions! Welcome back, Mr De Niro, sir. We hope your Tuesday is treating you well. (Rhetorical.

Never rat on your friends and always keep your mouth shut. Really wish we could! Yes, Mr De Niro, sir, but, you see this means the rats are completely out of the picture, just leaving us with our money spinner. Right, Mr De Niro โ€ฆ sir.

There are three ways of doing things around here: the right way, the wrong way and the way that I do it. [Exeunt: Stage right] Well, thatโ€™s odd? Mr De Niro wasnโ€™t interested in the quadrant nature to our problem solution โ€ฆ

If we are talking โ€œlayersโ€ (of functionality) again, onto the progress that yesterdayโ€™s Google Chart Image Chart Image Map Events Tutorial represented, then , it is logical โ€ฆ

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

โ€ฆ in the form of

  • user defined Javascript .. editable in a โ€ฆ
  • HTML textarea element

โ€ฆ and then the coding latching onto a document.createElement(โ€˜scriptโ€™) paradigm, to add Javascript clientside logic, on the fly.

Thereโ€™s a first time we can remember aspect to how we present these possibilities to the user. We present it in โ€ฆ

  • amongst the inhouse annotation options โ€ฆ as a โ€ฆ
  • โ€œrevealโ€ pairing of HTML5 details/summary element combination look โ€ฆ the first time we can remember aspect to that being โ€ฆ
  • only initially displaying within the details element innerHTML is a summary element nesting a single โ€œicon likeโ€ image (like the other โ€œinhouse annotationโ€ icon images) โ€ฆ but if clicked โ€ฆ
  • the details innerHTML has added to it a textarea element โ€ฆ

    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];

    //document.getElementById('tscript').value=decodeURIComponent(document.getElementById('tscript').innerHTML);
    }
    }

โ€ฆ from which document.createElement(โ€˜scriptโ€™) code onblur event logic emanates โ€ฆ


function tproc(ota) {
//alert(ota.value);
var tag = document.createElement('script');

Google Chart Image Chart Image Map Events Tutorial

Google Chart Image Chart Image Map Events Tutorial   ๐Ÿ”

We really like HTML image maps, and it occurred to us with yesterdayโ€™s Google Chart Image Chart Image Map Tutorial we were hiding its light under some bushel somewhere, because โ€ฆ

  • yesterday we introduced with only the onclick event coded for in the HTML area subelements to the map parent element โ€ฆ linked to an โ€ฆ
  • associated img element โ€ฆ via an โ€ฆ
  • attribute called usemap โ€ฆ and two aspects, at the very least, to stuff under the bushel are โ€ฆ
    1. many more events than onclick can be defined as you define the area subelements โ€ฆ and hereโ€™s the kicker โ€ฆ
    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 wonโ€™t if you, as a programmer, turn that use of the usemap attribute on and off like a tap

โ€ฆ which, to our mind, represents the beeโ€™s knees of event management. So useful!

To tip our toes into this woooorrrrrlllllddd weโ€™ll show you some newly added area subelement event logics in a Google Chart Image Chart Radar Chart example below โ€ฆ


<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>

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


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);

Do you like to come at explaining things in layers? Sort of like the analogy โ€ฆ

  • you start a project thinking of it in terms of โ€œ2Dโ€ โ€ฆ and then to move forward โ€ฆ
  • you spend a day making it work for โ€œ3Dโ€ (and keep the โ€œ2Dโ€ working as well)

โ€ฆ or โ€ฆ

  • you start a web application project thinking of only working via a URL entered on the web browser address bar โ€ฆ and then to move forward โ€ฆ
  • 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 โ€œpicturesqueโ€ but โ€œkinda dumbโ€ (as far as โ€œaction itemsโ€ go) image we have coming off the interfacing to Google Charts Image Chart. Where can we go here?

Google Chart Image Chart Dynamic Icons Tutorial   ๐Ÿ”

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 โ€ฆ

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

We had that certain โ€œWow!โ€œ factor going as we remembered our stateโ€™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 todayโ€™s tutorial picture.

Weโ€™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 โ€ฆ

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|INโ€™

Weโ€™ll leave yesterdayโ€™s Google Chart Image Chart Radar Chart Tutorial angled text predilections for now, given weโ€™ve got until Tuesday until tswhtf so to speak. Letโ€™s today remedy the concern we had when we presented Google Chart Image Chart Broadcast Talk Context Tutorial regarding, the at the time new, โ€œBroadcast Talkโ€, concept โ€ฆ

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

โ€ฆ and offer a way to help the โ€œBroadcast Talkโ€ demonstrator โ€œspeakโ€ during their demonstration, effectively. In so doing, we are going to add to โ€ฆ

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

โ€ฆ via a new โ€œmiddle of three slideโ€ โ€ฆ

Google Chart Image Chart Radar Chart Tutorial   ๐Ÿ”

Onto yesterdayโ€™s Google Chart Image Chart Box Chart Tutorial, today we have a two part stepping forward via new โ€ฆ

  • Radar Chart interfacing for Google Charts Image Chart โ€ฆ and โ€ฆ
  • 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 canโ€™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. Whoโ€™s is that question? And whatโ€™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 olโ€™ โ€ฆ pardon, Mr De Niro โ€ฆ good and well respected Javascript transform rotations โ€ฆ not with a triple pike, Mr De Niro, but youโ€™re awfulllllly close, Mr De Niro, sir โ€ฆ rather, we throw in a couple of translations โ€ฆ no, not Latin, Mr De Niro โ€ฆ 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 itโ€™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, hereโ€™s the updated Javascript parameterization โ€ฆ

โ€ฆ that goes into helping make thechanged latest draft image_vennโšซhtml 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 โ€ฆ

<style>

#fsangle { background-image: url("data:image/svg+xml;utf8,<svg xmlns='//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 textboxโ€™s purpose, and we do dislike set aside labels, these days. Itโ€™s also a way to explain the textbox for mobile users who do not get a hovering message to help. Itโ€™s also got an internationalization feel to it, using the degree sign emoji ยฐ (ie. &#176; or that \u0080 UTF-16 Encoding style of definition suitable for CSS styling usage) to both associate the units weโ€™d want, as well as that we are asking for an angle. Clockwise or anticlockwise, alas, comes down to user experience!

Google Chart Image Chart Colour Tutorial   ๐Ÿ”

Restricting you creatives to โ€œinhouse annotationsโ€ of the โ€œgray varietyโ€ might be seen as a bit boooorrrriiiinnnngggg! And so, onto the progress up to yesterdayโ€™s Google Chart Image Chart Rubber Banding Tutorial, today weโ€™ve added a โ€ฆ

  • colour picker โ€ฆ way user can define an โ€œinhouse annotationsโ€ colour โ€ฆ and while we were at it โ€ฆ
  • as far as text โ€œinhouse annotationsโ€ go weโ€™ve added a counterclockwise from the horizon, in degrees, way to define an angle the text should be placed at โ€ฆ and โ€ฆ
  • weโ€™ve stopped closing off the text font size dropdown too early, allowing the user to mix it up with their annotations, and so โ€ฆ

    We now recommend, for those users pushing the boundaries of functionality, to gather all their โ€œinhouse annotationsโ€ together before any โ€œgraphical canvas annotationsโ€ are thought about.

Which begs the question โ€ฆ

Where do you get it?

Well, here, via โ€ฆ dare we say it?! โ€ฆ โ€ฆ via โ€ฆ

Mantissa Madness Monday

Both colour and degree counterclockwise angle became โ€œMantissa Madness Mondayโ€ 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 โ€ฆ while โ€ฆ kind of crazily โ€ฆ
  • 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 โ€œMantissa Madness Mondayโ€ (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 โ€ฆ

<?php

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

Barracking for Hairtie United โ€ฆ
You little beauty, Untied!

And so, further to yesterdayโ€™s Google Chart Image Chart Circle Annotation Tutorial we have this non-mobile โ€œRubber Bandingโ€ inhouse annotation functionality included in ourchanged latest draft image_vennโšซhtml 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 thereโ€™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 todayโ€™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 โ€ฆ

  1. change looking for a โ€œtouchstartโ€ event, and instead look for a โ€œtouchdownโ€ event for a document.body scope (else we might have restricted the โ€œscopeโ€ to just document.getEleementById(โ€˜myvennโ€™) 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 โ€œdiscrete clickโ€ user behaviour we are targeting โ€ฆ as well as โ€ฆ
  2. start checking that the co-ordinates calculated fall into the range of the Google Charts Image Chart image dimensions โ€ฆ doh!

Did you know?

Well โ€ฆ we didnโ€™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 โ€ฆ

Today, we add โ€ฆ

  • open circle
  • filled circle

โ€ฆ annotation possibilities onto the โ€œBroadcast Talkโ€ work in yesterdayโ€™s Google Chart Image Chart Broadcast Talk Context Tutorial.

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 โ€ฆ

  • once a user has that โ€œMore Annotationโ€ annotating happening โ€ฆ offer the chance to โ€ฆ
  • Broadcast โ€ฆ their work as it happens, dynamically โ€ฆ
  • to an emailee list audience

โ€ฆ and weโ€™re calling this โ€ฆ

Broadcast Talk

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

Anyway, we hope you try out the new arrangements in ourchanged seventh draft image_vennโšซhtml 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 olโ€™ TwentyTen theme 404.php which now includes โ€ฆ

Further to yesterdayโ€™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 โ€œstatistical linesโ€, regarding interfacing to Google Charts Image Chart โ€ฆ

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

โ€ฆ the latter being like a โ€œparasiteโ€ 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 havenโ€™t stopped our โ€œretweakingโ€. We might โ€œretweakโ€ in the morning or we might โ€œretweakโ€ over a coffee break or we might โ€œretweakโ€ at supper time, but the end result is, well, youโ€™re reading it now!

Google Chart Image Chart Pie Chart Tutorial   ๐Ÿ”

As we intimated in yesterdayโ€™s Google Chart Image Chart GraphViz Chart Tutorial โ€ฆ

start with an at least two part โ€œinhouse phaseโ€ of additional โ€œextra to textโ€ annotation functionality possibilities โ€ฆ

โ€ฆ we would return! And so, here thou lingers. Itโ€™s โ€œpart twoโ€ day, even bigger than โ€œBen Hurโ€ in certain outback towns weโ€™re a little bit shy to divulge until we get to know our readers that little bit better.

Yes, we are dovetailing with work weโ€™ve done in the past using the excellent โ€ฆ

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

    โ€ฆ annotating modus operandi

โ€ฆ can be part of the arrangements. It works that the Annotation Helper is opened โ€ฆ

  • in a new โ€œknown aboutโ€ popup window โ€ฆ looking out for โ€ฆ
  • parent based โ€œimgโ€ element (in the modus operandi we use, calling it, regarding the parent top left image) โ€ฆ so as to be able to โ€ฆ
  • populate its canvas element with a clone of that calling โ€œimgโ€ graphical content โ€ฆ but add into the mix โ€ฆ
  • menu driven annotation functionality which can change that canvas look and underlying data โ€ฆ and โ€ฆ
  • the caller can keep track of this and arrange, or not, for these changes to be reflected back at its top left โ€œimgโ€ element โ€ฆ the catch being โ€ฆ
  • the โ€œwithin range of GET argumentโ€ 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 yesterdayโ€™s (and before) work โ€ฆ 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 โ€ฆ

  • Normal
  • 3D
  • Concentric

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

Today we have two strands of forward progress, onto the progress up to yesterdayโ€™s Google Chart Image Chart Scatter Chart Tutorial, they being โ€ฆ

  • establish a new interfacing to GraphViz Chart โ€ฆ

    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.

    โ€ฆ a chart looking a bit like Organization Charts โ€ฆ

    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 โ€œinhouse phaseโ€ of additional โ€œextra to textโ€ annotation functionality possibilities โ€ฆ just starting with โ€ฆ

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 โ€ฆ

  • HTML div (defining a box with defined dimensions) for a nested SVG element containing the line definition using percentage dimensions

โ€ฆ in the past, for when we needed to do this. But, today, weโ€™d like to thank this great webpage for its suggestion to involve linear gradients โ€ฆ


<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 {

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 youโ€™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 โ€ฆ

  • song obsessions โ€ฆ
  • earworms you need to salve

โ€ฆ 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.

As far as this WordPress blogโ€™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 PHPโ€™s GD image library as per โ€ฆ

Google Chart Image Chart Venn Chart Interfacing Primer Tutorial   ๐Ÿ”

So, moving on from Google Charts Image Chart Map Charts, today, letโ€™s turn our attention to Google Charts Image Chart Venn Charts which we were dead set curious about given work weโ€™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 youโ€™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, didnโ€™t you?! Didnโ€™t you!?! Well, the answer is โ€œGryffindor Slytherin Ravenclaw Hufflepuff Junior Business Collegeโ€ โ€ฆ 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 olโ€™ 404.php has been woken up to address via โ€ฆ

<?php

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

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 โ€œone lineโ€ calling URL! Whoโ€™d have believed it! Shiver me timbers!

Well, itโ€™s early days with this Venn Chart interfacing where we allow for โ€ฆ

  • circle (think up to three) definition โ€ฆ and the rest, in this first draft (hoping youโ€™ve done some reading) โ€ฆ
  • legend and title and colour selection user definitions dumped into a fairly unfriendly โ€œthe restโ€ Javascript prompt entry we ask of the user should they go ahead with the previous definition โ€ฆ and โ€ฆ
  • sharing and collaboration email and SMS functionality
