Hello,
I am a newbie to Matplotlib and all Python numeric stuff, so sorry if it is a FAQ.
I've installed NumPy 23.1, SciPy 0.3 and Matplotlib 54.1. Python is 2.3.4. The problem I have is that none of backends works properly.
TkAgg -- works fine from console, but if ran from IDLE or PythonWin it creates a window border only, does not populate it with plot. If I try to move the plot window whole python session crashes with generic runtime error message (windows error message box with a single Ok button).
WX/WXAgg -- both don't work from console -- show empty window, cursor turns in hourglass when it is over plot window. From GUI app (IDLE/PythonWin) it seems to work at first glance -- plot gets created, but the plot window can not be closed with either Alt-F4 or mouse. It just does not react on close command. Moreover, python objects corresponding to window seems to get destroyed when I try to close window, because if I do few plots commands without trying to close the window, new plots appear in first window, however as soon as I try to close the window (it won't close, remember?), new plots will open new window. That second window can be closed, but first one still remain unclosable.
GTK/GTKAgg -- can't really try that one, because it requires compiling GTK, and we don't have compiler yet.
Any ideas how that can be fixed, work arounded, debugged? I am pretty comfortable with debugging Python code, but as I said I don't have C compiler yet, so can't debug extensions.
This behavior observed on brand new computer with freshly installed Win XP. The same behavior I am observing on my a bit old Win XP laptop.

Kirill,
I've recently returned to Matplotlib and Scipy (and
happy to be back!!!). I had the same problem and
solved it by putting the lines
import matplotlib
matplotlib.use('WXAgg')
before the usual import
from matplotlib.matlab import *
This worked for all of the example code.
If you don't have the examples, which are not included
in the Windows installer, go back to the download page
again and grab the .zip file. This includes numerous
examples that you should be able to run with the two
lines mentioned above.
Hope this helps.

Barry, thanks a lot for your input, however I did try WXAgg, as well as WX and TkAgg and none of them works for me. One thing I forgot to mention in my previous e-mail though. I am using interactive mode. I just tried the same experiment in non-interactive mode, and WX works fine. However we are mostly interested in interactive mode, because we mostly use plotting for debugging purposes.

Try running with "idle -n" rather than just "idle" by changing the
properties of a copy of the idle shortcut.
TkAgg is know to work with:
python
idle -n
IPython
TkAgg is know not to work with:
SciTE
pythonw
Pythonwin
idle

Todd Miller
