A basic Radial Scatter chart

This goes in the documents header:

<script src="RGraph.common.core.js"></script>
<script src="RGraph.common.dynamic.js"></script>
<script src="RGraph.common.tooltips.js"></script>
<script src="RGraph.rscatter.js"></script>

Put this where you want the chart to show up:

<canvas id="cvs" width="500" height="500">
    [No canvas support]
</canvas>

This is the code that generates the chart:

<script>
    window.onload = function ()
    {
        var data = [];

        for (var i=0; i<360; i+=2) {
            data.push([i * 2, i, 'red']);
        }

        var rscatter = new RGraph.Rscatter({
            id: 'cvs',
            data: [data],
            options: {
                textAccessible: true
            }
        }).draw();
    };
</script>
