3D pcolor/pclormesh plot in matplotlib

1. My attempt

http://i8.tietuku.com/90d045a6c2375474.png

And I want to plot the value in the Z-axis.

For example, If I want to plot the altitude of this area, using 3d pcolor plot, I can get a figure just like the real terrain.

2. My result

For now, I can plot 3-d plot of this area using

Code 

import mpl_toolkits.mplot3d.axes3d as axes3d
fig,ax = plt.subplots(subplot_kw=dict(projection='3d'),figsize = (12,8))
ax.plot_surface(xx, yy,value,rstride = 1,cstride = 1,\
            cmap=plt.cm.Spectral_r,linewidth = 0)

Result

Can some one offer some advice to plot 3-d based on each grid value (like a 3-d histogram)?

Update

A little question added here, how to change the xticks and yticks in 3-d axes?
