3D plotting

Hello,

I have 2D array where each (x, y) cell represents the height of that point on the Z axis (you can think of it as the map of some mountain chain).
I'd like to get the plot_surface() of this data. What I don't understand in particular is the content of the X, Y ,Z array parameter in my particular example.

Can anybody elaborate on this please?

Thanks!
Claudio
