A basic example of the drawing API text object being used as a link

[No canvas support]

This goes in the documents header:
<script src="RGraph.common.core.js"></script>
<script src="RGraph.common.dynamic.js"></script>
<script src="RGraph.drawing.text.js"></script>
<script src="RGraph.line.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>
    new RGraph.Bar({
        id: 'cvs',
        data: [4,8,6,3,5,2,6],
        options: {
            xaxisLabels: ['Monday','Tuesday','Wednesday','Thursday','Friday','Saturday','Sunday']
        }
    }).draw();

    new RGraph.Drawing.Text({
        id: 'cvs',
        x: 575,
        y: 210,
        text: 'Read more...',
        options: {
            font: 'Arial',
            bold: true,
            halign: 'right',
            valign: 'bottom',
            colors: ['blue'],
            link: 'http://www.google.com',
            linkTarget: '_blank', // , // Default is _self
            textAccessible: false,
            bounding: true,
            boundingStroke: 'transparent'
        }
    }).draw();
</script>
