[Matplotlib-users] Use of Pyplot in a GUI script

I don’t really want a GUI application it this case. What I’m usually wanting is run pyplot with a file open dialog and a file save dialog. The file dialogs are important since I’m importing lots of json files and it would be a mess to try to type lots of long file names. I’ve tried several options including easygui, Tk and pyqt4. In theses cases, I can run them so long as I’m in an ipython console. However, as soon as I try to run from the terminal, I get a crash. I’ve managed by avoiding pyplot, but it is much nicer than using matplotlib without it.

However, that rule actually only needs to be strictly followed when you are embedding the matplotlib's canvas into your own instantiated Window object. If you are embedding GUI elements into a matplotlib figure window, you actually can still utilize pyplot (but very carefully).
