Bill, that is correct.

First a very basic question, is it possible to use Java3D
but not have the effect of 3D? that is to say, to make
the display flat just like the 2D, with a simple square
box with every thing projected on the X-Y plane
without foreshortening or the scales and their labels
all drawn with an angle w.r.t the XY plane.
I can't find a simple "switch" (something
like "GraphicsModeControlJ3D.setMode2D(true)" )
nor could I find any answer in the archive perhaps due to
not having the right key words.
People looking for a 2D graph just want something flat.

I will keep this in mind. So far my priorities are this in
descending order:
1) 2D x-y line plots
2) 2D contour plot of maps
3) 3D rendation of a 2D map
4) data of a function in 3D domain.
