Jason sent me this possibility:
1.
Plot it in 3d using one of the many 3d plotting functions such as surf
(surface plotting), mesh (mesh plotting), or plot3 (line plotting in
3d).
2.
Use the "view" command with 2 angles to get the right direction of
view. When you do this right, a 3d plot looks like a 2d color plot.
Example Octave Code:
peaks
view([90 0])
view([0 0])
view([90 0]) is clipboard1.png
view([0 0]) is clipboard2.png
The
view command takes an vector of 2 arguments that sets two angles,
[azimuth elevation].
As a newbie, this might take me awhile to digest. Thanks for taking the time to reply.
