I've searched a bit in the FAQ, since in the last days I'm struggling with the show and close command.
I've got a function that calculate values to plot. I calculate plot, use show command and everything goes fine.
I close the figure recalculate values and then replot and everything freezes because the show command seems still active.
I've tried to start IDLE using -n option but no solution. the plots freezes and I loose all calculations, and then I have to restart. reload etc..
I tried also to turn interactive off but no way of solving.
I'm using WIN XP
python 2.5
numpy 1.01
scipy 0.52
matplotlib 0.87.7
and I don't want to come back to matlab 
Since in matlab it's very common to calculate something, recalculate, plot etc. etc.
Any help would be very appreciated.
If needed I can post function and file I'm using in .tar

Try setting interactive : True in your matplotlibrc file, and restart your
idle -n session. Then you shouldn't even need to use the show() command, the
behavior will be very similar to matlab.

I've created a shortcut in the desktop to start idle-n
unsing C:\Python25\Lib\idlelib\idle.bat -n
then I changed matplotlibrc and set interactive: True
then started Idle, loaded the module and run.
At first I had this error message...
Traceback (most recent call last):

ImportError: No module named wx
naturally I installed WX wxPython2.8-win32-unicode-2.8.0.1-py25
and restart the demo. plots load faster (and I needed to use show). but then I recalculated and restart and everything crashed again 
I'm frustrated .. any hints
And sorry for bother I dont' want to get back to matlab
Giorgio
It worked !!!!
I dont' know why , probably i dind't restart correctly after changing config but with the setting you suggest it went fine.
THANKS !! You SAVED my DAY !!
Giorgio
I see. When you use idle, you should set backend : TkAgg in your rc settings.
The reason for this is discussed in the matplotlib users manual, see
http://matplotlib.sourceforge.net/users_guide_0.87.7.pdf.

I've seen that it also works with
WxAgg version 2.8.0.1 for python 2.5
I hope this information can be useful
