thanks, Don. I have been wondering what all these methods
with no JavaDoc at all do, setAspectCartesian(), 
GraphicsModeControlJ2D.getCurvedSize(), getPolygonMode() ...
by the way, I am now most puzzled by the ScreenBasedMode
of the scale, from the example (e.g. 42), it looks like
it is not the scale that is stationary to the screen, but
the coordinate system that the scales reflects. Is this
correct?

Yes it is a great tool. But I often heasitate in using the search
result because apparently some suggested code fixes have since been 
implemented in the release, so in general I don't know how
relevant the information in the archive is compared to the current
release.

thanks for taking time to answer. Does VisAD have a SPR/SCR
(Software Problem Report and Software Change Request) system
where one can see a list of change request listed?
