that you viewed something successfully. Is that correct?
Yes
Was this
displayer with mayavi or matplotlib?
I think it was displayed with matplotlib. A screenshot is attached.
It's matplotlib. Strange.
I suspect it was displayed with mayavi and that matplotlib is broken.
At the moment I think your fipy installation is fine and
works okay. You can go ahead and start working with fipy if you don't
mind living without a 1D plotting capability.
Would prefer to fix the problem completely and I will try to install Python 2.4 and follow the procedures in one of your previous emails.
Which version of matplotlib are you using? Do
>>> import matplotlib >>> matplotlib.__version__
to find out. You could be using a later version.
On the other hand, it is probably good to fix this problem so that
you can work through the examples effectively.
Does mesh1D.py display anything at all. Is it failing at the first
attempt at displaying something?
Can you try running the following file. This will give better error
messages.
A screenshot is in the attached PDF file. Screen output as below:-
