Eric and Thomas,
Thanks for your help. I was able to get it plotting MUCH faster. Here's my
code:
#!/usr/bin/env python
from pylab import *
from scipy import *
ion()
img = standard_normal((50,100))
image = imshow(img,interpolation='nearest',animated=True,label="blah")
for k in range(1,100):
img = standard_normal((100,100))
image.set_data(img)
draw()
Thanks again.
-Joey
