The following script works for me: import numpy as np import matplotlib.pyplot as plt image = np.random.random((100,50)) fig = plt.figure() ax = fig.add_subplot(1, 1, 1) ax.imshow(image, extent=[0,100,0,50]) plt.show() -- Damon McDougall http://www.damon-is-a-geek.com B2.39 Mathematics Institute University of Warwick Coventry West Midlands CV4 7AL United Kingdom ------------------------------------------------------------------------------ Don't let slow site performance ruin your business.
