Line chart FoldToCenter effect

This goes in the documents header:

<script src="RGraph.common.core.js"></script>
<script src="RGraph.line.js"></script>

Put this where you want the chart to show up:

<canvas id="cvs" width="600" height="250">
    [No canvas support]
</canvas>

This is the code that generates the chart:

<script>
    window.onload = function ()
    {
        var line = new RGraph.Line({
            id: 'cvs',
            data: [10,10,10,7,4,9,5,6,3,5],
            options: {
                textAccessible: true,
                scaleZerostart: true
            }
        }).draw()
          .foldtocenter()
    };
</script>
