+ * Class: $.jqplot.DateAxisRenderer
+ * A plugin for a jqPlot to render an axis as a series of date values.
+ * This renderer has no options beyond those supplied by the <Axis> class.
+ * It supplies its own tick formatter, so the tickOptions.formatter option
+ * should not be overridden.
+ *
+ * Thanks to Ken Synder for his enhanced Date instance methods which are
+ * included with this code <http://kendsnyder.com/sandbox/date/>.
+ *
+ * To use this renderer, include the plugin in your source
+ * > <script type="text/javascript" language="javascript" src="plugins/jqplot.dateAxisRenderer.js"></script>
+ *
+ * and supply the appropriate options to your plot
+ *
+ * > {axes:{xaxis:{renderer:$.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:
+ *
+ * > Code Result Description
+ * > == Years ==
+ * > %Y 2008 Four-digit year
+ * > %y 08 Two-digit year
+ * > == Months ==
+ * > %m 09 Two-digit month
+ * > %#m 9 One or two-digit month
+ * > %B September Full month name
+ * > %b Sep Abbreviated month name
+ * > == Days ==
+ * > %d 05 Two-digit day of month
+ * > %#d 5 One or two-digit day of month
+ * > %e 5 One or two-digit day of month
+ * > %A Sunday Full name of the day of the week
+ * > %a Sun Abbreviated name of the day of the week
+ * > %w 0 Number of the day of the week (0 = Sunday, 6 = Saturday)
+ * > %o th The ordinal suffix string following the day of the month
+ * > == Hours ==
+ * > %H 23 Hours in 24-hour format (two digits)
