Description Cassio 2010-11-03 12:57:12 UTC
Description of problem:
When plotting a figure with matplotlib it takes control of the main program shell (ipython) and doesn't return it.

Version-Release number of selected component (if applicable):
Name        : python-matplotlib
Arch        : i686
Version     : 1.0.0
Release     : 2.fc14
Size        : 22 M
Repo        : installed

Name        : ipython
Arch        : noarch
Version     : 0.10.1
Release     : 1.fc14
Size        : 4.1 M
Repo        : installed


How reproducible: Always.


Steps to Reproduce:
1. Run ipython -pylab
2. type plot()
3. type show()
  
Actual results:
The figure is shown (as a blank plot), however the input terminal of ipython stays busy. If I close the figure the control is still stuck. Pressing ctrl+c gives:

KeyboardInterrupt                         Traceback (most recent call last)

/home/cassio/<ipython console> in <module>()

/usr/lib/python2.7/site-packages/matplotlib/backends/backend_gtk.pyc in show(mainloop)
     76     if mainloop and gtk.main_level() == 0 and \
     77                             len(Gcf.get_all_fig_managers())>0:
---> 78         gtk.main()
     79 
     80 def new_figure_manager(num, *args, **kwargs):

KeyboardInterrupt: 


Expected results:

The control should be returned to the main ipython program once the figure has been displayed.

Additional info: I'm guessing this is a problem with the GtkAgg backend. Installing matplotlib-python-tk and creating the ~/.matplotlib/matplotlibrc file with backend:TkAgg property works around this issue.

Comment 1 Thomas Spura 2010-11-16 13:57:32 UTC
This seems to be fixed in the ipython git repo.

But unfortunately, I don't know how to properly backport the "fix", because ipython changed almost everywhere compared to 0.10.1.

So it would be better to use the workaround for now and wait for 0.11...

Sorry.
