Hello.

I want to plot the result of a calculation, show it, modify and
repeat. I have tried with pyplot interactive mode, see code:
http://pastebin.com/jsdsLN4z

The first plot shows fine, but from now on, all the new plots appear
in a new window and all of them are blank --including the first one! I
guess I am missing something. What could it be?

I am using Matplotlib 1.0.1 on Python2.5 and Windows XP.


Thanks,

David.
