A stacked Rose chart

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>
    var rose = new RGraph.Rose({
        id: 'cvs',
        data: [
            [4,5,8],
            [1,3,5],
            [2,6,8],
            [4,2,2],
            [4,3,5]
        ],
        options: {
            gutterBottom: 35,
            margin: 5,
            labels: ['Harry','John','Pete','Louise','John'],
            labelsAxes: 'n',
            textSize: 26,
            textSizeScale: 12,
            backgroundAxesColor: 'rgba(0,0,0,0)',
            backgroundGridRadials: 0
        }
    }).draw();
</script>
