matplotlib-users Mailing List for matplotlib

I ran into a nasty problem and was stuck until I realized that my numpy version was 1.3 when it should of been 1.5. But the errors never gave me an indication that this was the issue. I had added the new repository but the package was from some previous installation.  

I removed the old version of numpy and the reinstalled from the repository numpy 1.5 and matplotlib 1.0.0_15 and everything was happy crappy. I just thought I would save someone else from the headache.  

Is there a listing of incompatible versions in matplotlib for dependencies? Because even when I tried from source it didn't warn me it wouldn't work. 

iwm1-20:~/matplotlib # python setup.py install 
basedirlist is: ['/usr/local', '/usr']

It is working correctly just hope to save someone the headache. 

Thanks

Hi,

I'm not sure if you are still struggling about this problem. If you do, you 
might want to add an '.copy()' to 'y' in the pcolormesh as in the attached 
code. I think this is a matter of data vs. pointer to data field. The colorbars 
are generated in each step,  but the array 'y' is somehow used for all color-
meshes at some final point.

Kind regards and merry Christmas,
Matthias
