[flexcoders] Plot Graph and One Plot Point

[Geoffrey]

I have a PlotChart that uses a DateTimeAxis for the x, and a 
LinearAxis for the y.  I get something strange when there is only 
one point to plot.  The point renders fine on the chart, but the 
horizontal axis renderer only shows one date (1/1/70), and that's 
not the date of the plot point.  I would imagine that it should be 
the same date as the plot point.

Here's my horizontal axis renderer code:
<mx:horizontalAxis>
  <mx:DateTimeAxis
      baseAtZero="false"
      dataUnits="milliseconds"
      labelUnits="days"/>
</mx:horizontalAxis>
<mx:horizontalAxisRenderer>
  <mx:AxisRenderer
      visible="true"
      labelRotation="0"
      canStagger="false"
      canDropLabels="true"
      showLine="true"/>
</mx:horizontalAxisRenderer>

Any ideas?

Thanks,
  Geoff
