A simple question with matplotlib plot window #22

Closed zhangqi-chen closed 7 years ago

zhangqi-chen commented 9 years ago

Hey, all, I have a question with matplotlib. When I run a simple code like this:

import matplotlib.pyplot as plt import easygui_qt as easy plt.ion() plt.plot([1,2,3]) easy.get_int()

after I enter the integer and close the qt window, the plot window just crashes and cannot be closed. Any ideas?

This won't happen when I use easygui. So tkinter does not have such issue.

Easygui_qt starts a QtApplication for each individual widget and closes it. My understanding of the Qt framework is that it allows only one QtApplication running at a time; closing it might very well be the cause of the plot window crash.

Thanks, so any ideas to solve this? Or I may turn to easygui probably.

aroberge commented 9 years ago

If easygui works for you, then I'd suggest to use it instead.

Which python interpreter are you using? If ipython, look up forcing the use of pyqt with matplotlib in ipython. there may simply be a conflict of gui backends.

I use spyder. I tried Ipython console in spyder and only if I use qt as gui backends, the window would crash. So I guess I just use inline or wx. Thanks a lot!
