SDK 2.0: Controlling the X Axis in rallychart
===

I'm trying to create a defect create/kill chart for defects using rallychart in SDK 2.0.  The X axis is time-- in this case either individual days, weeks or months.

I don't see any examples of how to control the X-Axis using rallychart.  How do you do it?  Do you use categories directly in highcharts?  How should you configure the data store?

In general, what are some ways to do time based graphs using rallychart?
