Re: getAxisScale() returns null


AxisScales are only created when ScalarMaps map directly to
XAxis, YAxis and ZAxis.  Since you are mapping to other
DisplayRealTupleTypes, you get a null AxisScale.  Mathias
has no problem because he maps directly to the Cartesian
Display types.  I wish this was otherwise, but that's the
way the system was designed.
