Re: [Tutor] Closing a matplotlib window after show()
Well, you are correct. Finally, my latest post to the MPL list caught the eye of John Hunter. I think he wrote MPL. The way out is interactive use. One problem I've had with Python packages they "seem" to based on some other product, which one is supposed to know. I sight Tkinter and now MPL. I last used MatLab five years ago, and wrote some simple programs in it, so at least I have a very modest idea of how it works. I may have to use it to grsp the interactive mode. This problem has been a difficult one get a grip on. I've had socket error problems, difficulty getting Matlab back up on my machine, a possible install problem, and a host of ambiguities about this use. The end is near.

Re: [Tutor] Closing a matplotlib window after show()
Hi, recently I have the same problem with Matplotlib. I wrote a wxpython program which can plot a graph when click a button. When I click the button first time, I got the plot correct, but when I closed the figure, and clicked the button again, the code crashed. I have to reopen the program, and the same problem happened. The solution is that put "import matplotlib.pyplot as plt" before you plot anything. Then everything works fine. I don't know why. It seems that when you close the figure, the imported module or function stop working. It has to be imported every time.

Re: [Tutor] Closing a matplotlib window after show()
When I installed matplotlib2.5 on my W7 machine last were a few error msgs about missing about missing files. Is that usual for matplotlib. BTW, I've posted details of my problem to the MPL list. Here I'm interested in the basic of install and use with IDLE, and not the details of the use of MPL. Supposedly an uninstall is provided by a Python setup tool. I hae not used it yet. The basic problem is the show(). One person checked out the examples I provided and found show() to operate fine. On my XP machine the program I'm modifying has plot code someone put in a year or two ago, and it all works fine. My code produces the desired plot, but gets hung up on show().

[Tutor] Closing a matplotlib window after show()
