# A bank of adjustable Gauge charts

These Gauge charts are adjustable and the center one can be animated by clicking the button below (it animates to a random value). The `centerx` and `radius` values are set explicitly so the sizes are fixed no matter what the size of the canvas is.

This goes in the documents header:

    <script src="RGraph.common.core.js"></script>
    <script src="RGraph.common.dynamic.js"></script>
    <script src="RGraph.common.effects.js"></script>
    <script src="RGraph.gauge.js"></script>

Put this where you want the chart to show up:

    <canvas id="cvs" width="500" height="250" style="border: 1px solid #ccc">
        [No canvas support]
    </canvas>

This is the code that generates the chart - it should be placed AFTER the canvas tag(s):
