A plugin for a jqPlot to render an axis as a series of date values.  This renderer has no options beyond those supplied by the Axis class.  It supplies its own tick formatter, so the tickOptions.formatter option should not be overridden.

Thanks to Ken Synder for his enhanced Date instance methods which are included with this code http://kendsnyder.com/sandbox/date/.

To use this renderer, include the plugin in your source

<script type="text/javascript" language="javascript" src="plugins/jqplot.dateAxisRenderer.js"></script>

and supply the appropriate options to your plot

{axes:{xaxis:{renderer:$.jqplot.DateAxisRenderer}}}

Dates can be passed into the axis in almost any recognizable value and will be parsed.  They will be rendered on the axis in the format specified by tickOptions.formatString.  e.g. tickOptions.formatString = ‘%Y-%m-%d’.

Accecptable format codes are:
