This Scatter chart shows the new line dash setting. It's not available in all browsers as of March 2014.

This goes in the documents header:

Put this where you want the chart to show up:
<canvas id="cvs" width="600" height="200">

<script>
    new RGraph.Scatter({

        data: [[1,8],[5,4],[6,3],[9,4],[18,5],[19,3],[20,5]],
        options: {
            xaxisScaleMax: 20,
            xaxisLabels: ['Jan','Feb','Mar'],
            tickmarksSize: 5,

        }
