You can do this either with calls to the setRange() methods of
your ScalarMaps to XAxis, YAxis and ZAxis, or by calls to
the setMatrix() method of your ProjectionControl (you can see
examples and in visad/examples/).

You can replace the RangeWidget by explicit calls to
ScalarMap.setRange() to control how your data depictions are
scaled. If you need user interaction via RangeWidgets, you
can add a ScalarMapListener to the ScalarMaps whose ranges
are set by RangeWidgets, and ensure that ranges are within
certain bounds in their mapChanged() methods.

Good luck,
