A Line chart with custom tickmarks

This chart has tickmarks (but no tooltips). They were achieved using custom events/drawing (which have now been incorporated into RGraph itself).

[No canvas support]

This goes in the documents header:
<script src="RGraph.common.core.js"></script>
<script src="RGraph.core.dynamic.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]
This is the code that generates the chart:
    new RGraph.Line({
        id: 'cvs',
        data: [[5,4,1,6,8,5,3], [4,8,6,1,3,5,7]],
        options: {
            xaxisLabels: ['Monday','Tuesday','Wednesday','Thursday','Friday','Saturday','Sunday'],
            marginLeft: 55,
            marginRight: 35,
            marginBottom: 35,
            marginTop: 35,
            yaxisScaleZerostart: true,
            xaxisLabelsOffsety: 5,
            tickmarksStyle: null,
            backgroundGridDashed: true,
            shadow: null,
            highlightStyle: 'halo',
            tooltips: function ()
                return '\0';
