The following trivial program is supposed to generate one plot per key press

from os import sys
from matplotlib import *
from numpy.random import rand
while True:
z=
Try something like this:
from os import sys
from matplotlib import *
from numpy.random import rand
fig= pyplot.figure(figsize=(8,8), dpi=120)
pyplot.show()
while True:
z= rand(20,20)
pyplot.imshow(z)
pyplot.draw()
chr= sys.stdin.read(1)
if chr=='q':
break
appologies - sys.stdin.read(1) blocks until you give it a new line
(Enter) that' s probably what you were having problems with.

anything displayed.
I noticed that you used pyplot.draw() instead of pyplot.show(). I've
checked the available documentation, but haven't been able to understand the
difference between these.
I should have mentioned that I'm

i guess that might be because the show command before the loop blocks
the program.
you can omit the line with show or start ipython with
ipython -pylab
both versions work
