A Line chart with highlights based on the X mouse coordinate

This goes in the documents header:

<script src="RGraph.common.core.js"></script>
<script src="RGraph.common.dynamic.js"></script>
<script src="RGraph.common.tooltips.js"></script>
<script src="RGraph.bar.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: [4,5,5,8,8,7,8,9,8,11,13,13,12,14,15,15,17,18,18,17,17],
            options: {
                tooltips: function () {return "\0";},
                tooltipsHotspotXonly: true,
                numxticks: 6,
                gutterLeft: 30,
                gutterRight: 30,
                labels: ['Monday','Tuesday','Wednesday','Thursday','Friday','Saturday','Sunday'],
                textAccessible: true
            }
        }).draw();
    };
</script>
