<h1>A Scatter chart using Date/Time values</h1>
<p>
This shows how you can use Date/Time values as X values with the Scatter chart. Although it's a Scatter chart it can also
show a line, as you can see. The chart has two lines, one of which is stepped.

This goes in the documents header:
<pre class="code">
<script src="RGraph.common.core.js"></script>
<script src="RGraph.scatter.js"></script>
</pre>
Put this where you want the chart to show up:
<pre class="code">
<canvas id="cvs" width="600" height="200">
[No canvas support]
</canvas>
</pre>
This is the code that generates the chart:
