[Matplotlib-users] IDLE, matplotlib and show command

From: Giorgio L. <gio...@ch...> - 2006-12-21 10:04:13

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):
  File "C:\Python25\Lib\site-packages\prove\demo.py", line 1, in <module>
    from pylab import *
  File "C:\Python25\lib\site-packages\pylab.py", line 1, in <module>
    from matplotlib.pylab import *
  File "C:\Python25\lib\site-packages\matplotlib\pylab.py", line 220, in 
<module>
    new_figure_manager, draw_if_interactive, show = pylab_setup()
  File "C:\Python25\lib\site-packages\matplotlib\backends\__init__.py", 
line 23, in pylab_setup
    globals(),locals(),[backend_name])
  File 
"C:\Python25\lib\site-packages\matplotlib\backends\backend_wxagg.py", 
line 19, in <module>
    import wx
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

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 !!

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

I see. When you use idle, you should set backend : TkAgg in your rc setting=
s.=20
The reason for this is discussed in the matplotlib users manual, see=20
http://matplotlib.sourceforge.net/users_guide_0.87.7.pdf.
