Hi,
Just some quick comments:


1. learn list comprehensions, they're far faster than regular loops.

data = [(i,j,int(numpy.random.random()*10))
               for i in range(XI) for j in range(JI)]

2. if you don't really need the triplets, but just the random part, just use:
Z = (numpy.random.random(XI*YI)*10).astype(int).reshape(Xl,Yl)

3. It's more efficient to use numpy.empty than numpy.zeros to initialize an 
array you're going to fill afterwards.

4. You may have found a bug in plot_wireframe, actually. The code doesn't look 
quite right. My understanding is that the 3d part is not really supported, 
either...


Hope it helps.
