[Matplotlib-users] imshow problem

[Luigi P. <lu...@mi...>]

Hi all!

I've just installed matplotlib on my workstation (without Numeric, only 
numarray). Trying to run the image plot examples, I get this error:


Exception in Tkinter callback
Traceback (most recent call last):
   File "<mypath>/lib/python2.3/lib-tk/Tkinter.py", line 1345, in __call__

ValueError: Array must be rank 2 or 3 of doubles


What's the problem?

Tanks in advance.
