A bipolar chart with a Gauge on the same page

This an example of two different charts (on two different canvases) on one page.

[No canvas support] [No canvas support]

This goes in the documents header:
<script src="RGraph.common.core.js"></script>
<script src="RGraph.common.dynamic.js"></script>
<script src="RGraph.bipolar.js"></script>
<script src="RGraph.gauge.js"></script>
Put this where you want the chart to show up:
<canvas id="cvs1" width="600" height="250">[No canvas support]</canvas>
<canvas id="cvs2" width="250" height="250">[No canvas support]</canvas>
This is the code that generates the chart:
<script>
    window.onload = function ()
    {
        var bipolar = new RGraph.Bipolar({
            id: 'cvs1',
            left: [4,8,6,4,3],
            right: [18,4,6,3,3],
            options: {
                textAccessible: true,
                labels: ['Luis','Peter','Joe','Hoolio','Gina']
            }
        }).draw();

        var gauge = new RGraph.Gauge({
            id: 'cvs2',
            min: 0,
            max: 100,
            value: 87,
            options: {
                textAccessible: true,
                textAccessiblePointerevents: false,
                adjustable: true
            }
        }).draw();
    };
</script>
