My starting point would be this example:

whatever data or function of x and y that you want. Using

import numpy as np
from mpl_toolkits.axes_grid1 import

a = ma.array([[1,2,3],[4,5,6]],mask=[[0,0,1],[0,0,0]])

cmap.set_bad(alpha=0.0)
imshow(a, interpolation='nearest', cmap=cmap)

Any thoughts?

Just divide through by '1000.' or '1000.0' (same thing).
If you write 3100/1000, you'll get '3' because you are doing integer math.
If you write 3100/1000.0, you'll get '3.1' because you are doing float math.
