Why can't you just overplot the 3-d plot but with one of the data arrays set to a level
such that it looks like a separate plot on one of the box sides. I just did it with my own
3-d plotter (which has a specified OPLOT keyword). Took about a minute. I created an
unrelated 2-d dataset and just set all the Z-values to 0 (you could do the same for the X-
or Y- values depending on which "box-side" you want to plot on. The T3D transformation
from the previous 3-d plot is used. In the event that the data ranges of your 2-d plot are
outside the existing 3-d curve you have already plotted, then why use the same graph? It
would be a confusing overplot.

Anyway.....
