I'd like to compare three vectors graphically, and I think surf is the function to use.
In exploring surf, I can't wrap my head around how to implement meshgrid. The variables I want to compare are all vectors of the same length, yet Z needs to be a matrix according to the documentation, and meshgrid is somehow involved.
X: 7627x1, range: 420 to 480
Y: 7627x1, range: -30 to -8
Z: 7627x1, range: 0.8 to 4.2
In all of the examples on the surf documentation page, the Z-axis is always symmetrical about 0. Can you use surf where the Z-axis minimum is 0?
If surf isn't what I want to use to do this, please point me in the right direction. I've also seen rectangular colormaps using filled in color gradients (i.e., not points or lines) comparing X vs. Y vs. Z (represented by color). Obviously, there's some interpolation happening in both this 2-d colormap as well as surf.
As a sample, how does one produce something like this sample, which is comparing X vs. Y vs. Z (denoted with a color ramp).
Thanks, everybody. As always, the help is much appreciated.
