# A graduated blue Gauge chart Gauge chart

This goes in the documents header:

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

Put this where you want the chart to show up:

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

This is the code that generates the chart:

    <script>
        window.onload = function ()
        {
            var gauge = new RGraph.Gauge({
                id: 'cvs',
                min: 0,
                max: 10,
                value: 7,
                options: {
                    backgroundColor: 'Gradient(white:#00a)',
                    textColor: 'white',
                    tickmarksBigColor: 'white',
                    tickmarksSmallColor: 'white',
                    redColor: 'rgba(0,0,0,0)',
                    yellowColor: 'rgba(0,0,0,0)',
                    borderInner: '#00c',
                    borderOuter: 'Gradient(blue:blue:blue:blue:blue:blue:blue:blue:blue:blue:blue:blue:blue:blue:blue:blue:blue:blue:black)',
                    adjustable: true,
                    textAccessible: true
                }
            }).draw();
        };
    </script>
