A stacked Rose chart

[No canvas support]

This goes in the documents header:
<script src="RGraph.common.core.js"></script>
<script src="RGraph.rose.js"></script>
Put this where you want the chart to show up:
<canvas id="cvs" width="600" height="400">
    [No canvas support]
</canvas>
This is the code that generates the chart:
<script>
    new RGraph.Rose({
        id: 'cvs',
        data: [ [4,5,8], [1,3,5], [2,6,8], [4,2,2], [4,3,5] ],
        options: {
            marginBottom: 35,
            margin: 5,
            labels: ['Harry','John','Pete','Louise','John'],
            labelsAxes: 'n',
            textSize: 26,
            labelsAxesSize: 12,
            backgroundGridRadials: 0
        }
    }).draw();
</script>
