PHP/Javascript/HTML Google Chart Scatter Chart Tutorial
Here is a tutorial that introduces you to Google Graphs API, or Google Chart Tools, and its Scatter Chart functionality, which is a way to represent discrete points. In Land Surveying, for instance, such a tool could be used to plot borehole positions in grid co-ordinates, perhaps overlaying a similar geophysical “underlay” map. Maps are full of discrete point requirements. Taken to the right small scale, cities on a map become “dots” or points. If this “blows your mind” or interests you, study fractals or perspective.
Google Chart Tools provide a perfect way to visualize data on your website. From simple line charts to complex hierarchical tree maps, the chart galley provides a large number of well-designed chart types. Populating your data is easy using the provided client- and server-side tools.
Let’s see some PHP code in live action for this tutorial where you define your scatter chart characteristics and data.
