[Matplotlib-users] plot window not rendering, hanging

[Darren D. <dd...@co...>]

Thank you to the people who are working on this project. I am beginning the transition from Matlab to Python, so I was excited to find matplotlib.

As John reported earllier:

Additionally, if I use the WX backend, the window launches but does not render the plot (the widgets are rendered.) I can close the window, but I dont recover the command line in IDLE. I exited all programs, and tried to uninstall matplotlib 0.53 to install 0.52. During the uninstall, I got a message that datetime.pyd (I wonder if I copied this name down incorrectly, I'm sorry) was in use and could not be deleted.

One other note: I havent been able to install the GTK runtime environment. I have been having a mess of dll conflicts with other files on my system path. I havent seen any advice on the web that would solve this problem. Can anyone point me in the right direction? The best advice I have seen is to specify a GTK_PATH environment variable, which should be searched for resources before defaulting to the PATH variable. I did this for both the system and user, but I am still getting the same conflicts. This concerns the quickstart advice for windows users on the matplotlib website. (One site even suggested deleting the conflicting dll's from the path in order to not block the GTK resources. Yikes.) 

Thanks again for matplotlib. I am finishing grad school in a few months. When I do, I would like to participate in the development if I can be of help.

Did you launch with idle -n?  Todd, perhaps you can add a FAQ here.  I
updated the backends.html.template section with the summary posted
earlier but this is getting damn close to a FAQ.

This is known bug on my TODO list; thanks for letting me know.

This is bizarre since a matplotlib uninstall shouldn't be messing with
datetime.pyd.  Are you sure you didn't accidentally click uninstall
for another package?

What do you mean?  The *best* time to develop matplotlib is with a
thesis defense looming.  Otherwise you'll just find yourself cleaning
your house for the 3rd time and playing addictive video games to
distract yourself.

I may have made a mistake here; I had to process a lot of new information 
this weekend. The impression I got was that datetime.pyd was hanging from 
an earlier process, not from the uninstall.

Is this the standard model for thesis writing? If it is, I am jealous. In 
my case, I spent three years building an experiment which now requires 3 
week spurts of around the clock work, with a lot of maintenance and writing 
of papers in between. I really prefer programming to playing video games. 
With programming you get to define your own puzzles and you have something 
useful when your done.

Anyway, I'll start looking at the source code, maybe there is something I 
can get started on.

I decided to learn python when my thesis was due.  Productive
procrastination is the best kind.
