Hi, I'm trying to superpose several pcolor plots but cannot find the right way. Hold on doesn't seem to work.
Also I would like each pcolor plot to have only one colour for all points instead of using a colormap, is that possible?
Thanks for your help !

You're still not helpful. The following creates two pcolor plots on the same axes:
pcolor(peaks)
hold on
pcolor(peaks(10))
So what did you do to cause matlab to open a new figure? Some code would be quite useful... also, what do you mean by a single color per plot? I will not ask why you'd want to do such a thing, but you can just set the z-data to a uniform value and apply any colormap.

Maybe you're having a problem because pcolor doesn't have the same number of "pixels" as what you passed in. See this code:
pcolor(rand(3,5)); % Show 3 by 5 grid of pixels - NOT!
