Bipolar chart wave() effect

[No canvas support]

This goes in the documents header:
<script src="RGraph.common.core.js"></script>
<script src="RGraph.bar.js"></script>
Put this where you want the chart to show up:
<canvas id="cvs" width="800" height="350">
    [No canvas support]
</canvas>
This is the code that generates the chart:
<script>
    data = [4,8,6,3,5,2,6,8,4,5,7,8];

    new RGraph.Bar({
        id: 'cvs',
        data: data,
        options: {
            textAccessible: true,
            backgroundGridVlinesCount: 0,
            linewidth: 0,
            shadow: false,
            hmargin: 7,
            colors: ['Gradient(pink:red:#f33)', 'Gradient(green:#0f0)'],
            labelsAbove: true,
            xaxisLabels: ['Jan','Feb','Mar','Apr','May','Jun','Jul','Aug','Sep','Oct','Nov','Dec'],
            clearto: 'white',
            variant: '3d',
            marginBottom: 90,
            axes: false
        }
    }).wave({frames: 60});
</script>
