    <h1>An image based Meter chart with background and needle images</h1>


    <p>
        This Meter uses CSS width/height units on the canvas tag to scale the whole Meter down (the image is 640x640 but the
        canvas is sized by CSS to 400x400).
    </p>
    <canvas id="cvs" width="640" height="640" style="width: 400px; height: 400px">[No canvas support]</canvas>

    This goes in the documents header:
    <pre class="code">
&lt;script src="RGraph.common.core.js"&gt;&lt;/script&gt;
&lt;script src="RGraph.common.dynamic.js"&gt;&lt;/script&gt;
&lt;script src="RGraph.meter.js"&gt;&lt;/script&gt;
</pre>
    
    Put this where you want the chart to show up:
    <pre class="code">
&lt;canvas id="cvs" width="640" height="640" style="width: 400px; height: 400px"&gt;
    [No canvas support]
&lt;/canvas&gt;
</pre>

    This is the code that generates the chart:
    <pre class="code">
&lt;script&gt;
    window.onload = function ()
    {
        var meter = new RGraph.Meter({
            id: 'cvs',
            min: 0,
            max: 9,
            value: 8.5,
            options: {
                centerx: 321,
                centery: 298,
                backgroundColor: 'rgba(0,0,0,0)',
                backgroundImageUrl: '/images/meter-image-sd.png',
                backgroundImageStretch: true,
                backgroundImageOffsetx: 0,
                backgroundImageOffsety: 0,
                scaleDecimals: 1,
                needleColor: 'rgba(0,0,0,0)',
                needleImageUrl: '/images/meter-image-sd-needle.png',
                needleImageOffsetx: -94,
                needleImageOffsety: -40,
                colorsRanges: [],
                tickmarksBigNum: 0,
                tickmarksSmallNum: 0,
                border: false,
                labels: false,
                textSize: 36,
                centerpinStroke: 'rgba(0,0,0,0)',
                centerpinFill: 'rgba(0,0,0,0)',
                anglesStart: 2.69,
