I'd better take a look at your program - might be a bug in
VisAD.  Could you please put your code and data in a jar
file (or compressed tar file) and ftp it to me as follows:
  login: anonymous
  password: email@address
  ftp> cd pub/incoming
  ftp> bin
  ftp> filename.jar
  ftp> quit
Then send me an email with the name of the jar file.

Clipping control is on my to do list.

I just added a method setAspect(double[] aspects) to
ProjectionControl to allow you to do this.  The aspects
array has length 2 for DisplayImplJ2D and length 3 for
DisplayImplJ3D.  It is now called in and in visad/examples.

You will get scales for any RealType mapped to XAxis, YAxis
or ZAxis.  You control the colors of these via the setScaleColor
method of ScalarMap.  For example:
  ScalarMap map2temp = new ScalarMap(temp, Display.XAxis);
  map2temp.setScaleColor(new float[] {red, green, blue});
Sorry to say there is currently no control over font size
for axis scale labels.
