Horizontal Bar grow() effect changing values

This is a demo of the grow() effect being passed new data and instead of growing from zero it grows from the old data to the new data supplied.

[No canvas support]

This goes in the documents header:
<script src="RGraph.common.core.js"></script>
<script src="RGraph.hbar.js"></script>
Put this where you want the chart to show up:
<canvas id="cvs" width="600" height="250">
    [No canvas support]
This is the code that generates the chart:
    hbar = new RGraph.HBar({
        id: 'cvs',
        data: [86,485,325,411,354,298,333],
        options: {
            xaxisScaleMax: 500,
            xaxis: false,
            backgroundGridHlines: false,
            backgroundGridBorder: false

    setInterval(function ()
        hbar.grow({data: RGraph.random.array(7, 0, 500)});
    }, 2500);
