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

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>
    window.onload = function ()
    {
        var line = new RGraph.Line({
            id: 'cvs',
            data: [4,8,6,3,5,2,6],
            options: {
                labels: ['Monday','Tuesday','Wednesday','Thursday','Friday','Saturday','Sunday']
            }
        }).draw()

        var text = new RGraph.Drawing.Text({
            id: 'cvs',
            x: 575,
            y: 220,
            text: 'Read more...',
            options: {
                textAccessible: false,
                font: 'Arial',
                bold: true,
                halign: 'right',
                'valign': 'bottom',
                colors: ['blue'],
                link: 'http://www.google.com',
                linkTarget: '_blank' // Default is _self
            }
        }).draw();
    };
</script>
