Canvasgraph is a project mainly written in JavaScript, it's free.
a simple javascript graphing class working with a canvas tag
h1. CanvasGraph
Paints simple graphs on a canvas tag.
h3. Configuration options
background: The canvas background colour (as CSS colour value) foreground: The line colour (as CSS colour value)
Nothing more, yet.
h3. Usage
All you need is to give your canvas tag an identifier (for example graph1) and add this to (the bottom?) of your page:
bc.
The second argument contains the data to be plotted. I don't test for invalid values so be sure it is only contains valid numericals.
To set configuration options, simply add a hash as third argument:
bc.
That's it.
