Re: [Matplotlib-users] where did my plots go?
Hi André, Have you tried to run your script from within IPython? That is, run ipython --pylab in your Terminal and %run your_script.py inside IPython. This always keeps the figures around for me, regardless of the presence of show().

Re: [Matplotlib-users] where did my plots go?
Hi All, Sort of hijacking my own thread here. I posted another issue yesterday or the day before, and this has caused me to find some bigger problems... Most likely, there was a change to your matplotlibrc file. There is a setting in there for interactive and by default, it is set to False. If you uncomment it and set it to True, you should get back the behavior you expected. You can also explicitly set the interactive mode to True from your scripts with a plt.ion() call before loading your other modules. I was having such problems with my setup (mac os 10.6.8, EPD 7.3[ python2.7 matplotlib 1.1.0]), I decided to completely wipe all my python installations in /Library/Frameworks/Python.framework/Versions/ I then re-installed EPD 7.3 I modified my matplotlibrc to backend : TkAgg interactive : True I have run with --verbose-helpful to verify that these options are used (at least at startup). But my plots still vanish as soon as the script is done :`( [that is me, a grown man, crying] I see I can use matplotlib.pyplot.isinteractive() to see that interactive is true. How can I print the rc param to check the backend? I haven't found this on google or in the matplotlib userguide yet. Also, any ideas? I am pulling hair out since of course I am supposed to be doing analysis for a talk next monday.

That's to be expected. You can make the script not to end until the
user ask for it explicitly:
raw_input('Press Enter when you are done')

My understanding was that changing

Is my understanding incorrect?

That is correct. If you have a call to show(), then the script should not
finish on their own until the windows are closed -- regardless of whether
or not interactive is True or False. The interactive setting should
only dictate whether or not the script execution pauses or not at the call
to show(). Have you tried a different backend as a temporary work-around
such as QTAgg, QT4Agg, GTKAgg, TkAgg?

This behavior is observed with both TkAgg and MacOSX.
I don't have pygtk or pyqt installed, so couldn't test the others.

Inspired by a related thread - which Goyo just answered, I tried the following import matplotlib.pyplot as plt plt.plot([1.6, 2.7]) In an interactive python session (also in ipython), this produced the plot, and it stayed up until I closed it. I converted it to a little script === #!/Library/Frameworks/Python.framework/Versions/Current/bin/python import matplotlib.pyplot as plt plt.plot([1.6, 2.7]) print plt.get_backend() plt.show() === this prints to screen TkAgg, but the plot disappears as soon as the script finishes.

Then the script is supposed to keep itself alive, after executing the
last statment, until the plot windows are closed? Does not work that
way for me (tkagg, qt4agg and gtk*) and I wouldn't expect that.
BTW this may be better than using raw_input:
import matplotlib.pyplot as plt
plt.ion()
plt.plot([1.6, 2.7]) # The plot windows shows up.
# Do stuff, even user interaction, more plots, etc.
# ...
# Wait until all plot windows are closed.
plt.ioff()
plt.show()

Then the script is supposed to keep itself alive, after executing the last statment, until the plot windows are closed? Does not work that way for me (tkagg, qt4agg and gtk*) and I wouldn't expect that. Yes, this is how things used to work on my mac (1 week ago). After upgrade, no longer works this way. Reverting to old compilation - still no longer works. BTW this may be better than using raw_input: import matplotlib.pyplot as plt plt.ion() plt.plot([1.6, 2.7]) # The plot windows shows up. # Do stuff, even user interaction, more plots, etc. # ... # Wait until all plot windows are closed. plt.ioff() plt.show() This reproduces (as far as I can tell) the exact behavior I used to have. Interesting to note. If I have interactive : True in my matplotlibrc file, and then import matplotlib.pyplot as plt # do everything I used to do # including call functions that do other plots etc. plt.ioff() plt.show() this also produces the above behavior (what used to work). So, if I am in interactive mode, then matplotlibrc opens and closes the figures for me. However, if after making all my plots, just before calling plt.show(), I turn off interactive mode, then the plots stay open. This does not follow the logic I would expect - ie interactive means I would have to close the figures interactively. But it gives the behavior I have come to expect. Now back to my other problems (I'll start a new thread).

[Matplotlib-users] where did my plots go?
Hi All, I have mac os x, 10.6.8, enthought distribution. I recently upgraded from the 6.2 to 7.3 EPD. Previously, I had a script which would manipulate some data, and as soon as the command plt.figure() was issued, the plot would show up. I could then continue along with the analysis (I wrote an interactive script) and plots would be updated, and new plots would show up (when I issued a command like re-sizing the plot limits. This no longer happens, and now the plots are not drawn until the very end of all the analysis. But of course this defeats the purpose of having an interactive analysis session. I do have plt.show() at the very end of the script. In case it may matter, my main script loads another one as a module. (But this is how it was before when it worked). I am not sure what has caused this to change. I have tried the follwing - restart computer in case there were just some gui problem - re-install the EPD 7.3 and EPD 6.2 (in that order) - use the older 6.2 installation to run the script all of these fail to produce the behavior I previously had. It would be great to sort this out.
