A grouped Bipolar chart

[No canvas support]

This goes in the documents header:
<script src="RGraph.common.core.js"></script>
<script src="RGraph.bipolar.js"></script>
Put this where you want the chart to show up:
<canvas id="cvs" width="600" height="450">

    new RGraph.Bipolar({
        id: 'cvs',
        left:  [[1,2,3],[4,5,6],[7,8,9]],
        right: [[1,2,3],[4,5,6],[7,8,9]],
        options: {
            vmargin: 30,
            yaxisLabels: ['Alf','Barry','Charlie'],
