    <p>
        This Bar chart uses the custom RGraph ondraw event to add highlight to each bar.

    This goes in the documents header:
    <pre class="code">
&lt;script src="RGraph.common.core.js"&gt;&lt;/script&gt;
&lt;script src="RGraph.bar.js"&gt;&lt;/script&gt;
</pre>
    
    Put this where you want the chart to show up:
    <pre class="code">
&lt;canvas id="cvs" width="600" height="250"&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 bar7 = new RGraph.Bar({
            id: 'cvs',
            data: [[47,75],[32,74],[71,85],[25,19],[23,71],[81,59],[43,130],[23,20]],
            options: {                    textSize: 14,
                gutterLeft: 45,
                colors: ['#494949','#35A0DA'],
                labels: ['Alf','Bert','Craig','Dan','Edgar','Fred','Gary','Harry'],
                ylabelsCount: 3,
                numyticks: 6,
                backgroundGridAutofitNumhlines: 3,
                backgroundGridVlines: false,
                backgroundGridBorder: false,
                hmargin: 5,
                strokestyle: 'rgba(0,0,0,0)',
                textAccessible: true,
                shadow: true
            }
        }).on('draw', function (obj)
        {
            var len = obj.coords.length;

            for (var i=0; i&lt;len; ++i) {

                var x = obj.coords[i][0];
                var y = obj.coords[i][1];
                var w = obj.coords[i][2] / 2;
                var h = obj.coords[i][3];

                obj.context.fillStyle = 'rgba(255,255,255,0.15)';
                obj.context.fillRect(x,y,w,h)
