I am sure this is a well know issue, so please feel free to just give a link if the answer and solution are long. I have a newly installed matplotlib installations running on Windows XP using Python 2.5.4. When I execute a simple 4 line example (copied directly from the PyPlot tutorial) in either PythonWin or IDLE, , it works fine and I terminate by right clicking on the generated figure and doing a Close. However, when I rerun the code from the IDE (makes no difference if I use PythonWin or IDLE) the figure hangs and eventually I get an abnormal exit and crash out of the IDE (in PythonWin there is a dialogue box that says “Runtime Error” in pythonwin.exe. This makes debugging in an IDE very clumsy, because I need to exit and restart it every time I run python code.
The test code is simply:
import matplotlib.pyplot as plt
plt.plot([1,2,3])
plt.ylabel('Some Numbers')
plt.show()
import matplotlib.pyplot as plt
plt.ion()
plt.plot([1,2,3])
plt.ylabel('Some Numbers')
plt.show() # You don't have to call show() in interactive mode though

I'm using the TKAgg backend, I guess there will be problems with other
interactive backends.

Interactive mode works for me in an IDLE shell:
import matplotlib.pyplot as plt
plt.ion()
plt.plot([1,2,3])
plt.ylabel('Some Numbers')
plt.show() # You don't have to call show() in interactive mode though
