A time based SVG Scatter chart

This Scatter chart has been configured to use datetime values for the X coordinates, the title has been customised slightly and the points have tooltips. The background grid has no vertical gridlines.

This goes in the documents header:
<script src="RGraph.svg.common.core.js"></script>
<script src="RGraph.svg.scatter.js"></script>
Put this where you want the chart to show up:
<div style="width: 700px; height: 250px" id="chart-container"></div>
This is the code that generates the chart:
<script>
    data = [
        {x:'23:59 15-01-2012', y:5, tooltip: 'Yunka'},
        {x:'2012 15th February', y:6, tooltip: 'Ally'},
        {x:'Mar 15 2012', y:6, tooltip: 'Fred!'},
        {x:'2012/04/15', y:6, tooltip: 'Tom!'},
        {x:'2012-05.15', y:5, tooltip: 'Rachel!'},
        {x:'2012 June 15', y:4, tooltip: 'Jone!'},
