# A Meter chart

This goes in the documents header:

    <script src="RGraph.common.core.js"></script>
    <script src="RGraph.common.dynamic.js"></script>
    <script src="RGraph.meter.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 meter = new RGraph.Meter({
                id: 'cvs',
                min: 0,
                max: 100,
                value: 75,
                options: {
                    anglesStart: RGraph.PI + 0.5,
                    anglesEnd: RGraph.TWOPI - 0.5,
                    linewidthSegments: 15,
                    textSize: 16,
                    strokestyle: 'white',
                    segmentRadiusStart: 155,
                    border: 0,
                    tickmarksSmallNum: 0,
                    tickmarksBigNum: 0,
                    adjustable: true,
                    needleRadius: 135,
                    textAccessible: false
                }
            }).on('beforedraw', function (obj)
            {
                RGraph.clear(obj.canvas, 'white');
            }).draw();
        };
    </script>
