When you do that, how does this show up in the coordinates?

Hi Dan,

Mathcad allows for as many coexisting simultaneous axis as you care.

As for 3D, this is called a contour plot (which can be done either
flat, or with relief). Excel will do this too (but with no particular
panache).

Seeing you are funds challenged, search the web for OpenDX (an IBM
project deeded to the public domain, and otherwise called Data
eXplorer). It can do the same thing. There is also a package called
XD3D, that is also from the OpenSource community.

The IBM package is the one most used by the research community; or at
least the ones I've been attending for 7 years.

I already know what a static 3D plot would like like. But to put it in
motion, including the illustration of the forward and reflected length
over distance x; showing the surface of periodic waves for each value
of x; that would be a nice visual.

Hi Dan,

I've already offered that solution. I have been using OpenDX to do
this for some time now. Have you looked at my suggestions?
