Odometer chart Grow effect

This goes in the documents header:

<script src="RGraph.common.core.js"></script>
<script src="RGraph.odo.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 odo = new RGraph.Odometer({
            id: 'cvs',
            min: 0,
            max: 100,
            value: 90
        }).grow();
        
        
        setTimeout(function ()
        {
            odo.value = 50;
            odo.grow();
        }, 3500);
    };
</script>
