plot won't show with plt.show(block=False) #6979
Description
In IPython environment, When I make plot using plt.show(block=False), the plot won't show at all. And after the script is finished, if I press CTRL+D (to exit), then the plot will show up.
- Matplotlib version, Python version and Platform (Windows, OSX, Linux ...)
Matplotlib 1.5.1, Python 3.5.2, IPython 5.1.0, Ubuntu - How did you install Matplotlib and Python (pip, anaconda, from source ...)
Miniconda - If possible please supply a Short, Self Contained, Correct, Example
that demonstrates the issue i.e a small piece of code which reproduces the issue
and can be run with out any other (or as few as possible) external dependencies. - If this is an image generation bug attach a screenshot demonstrating the issue.
- If this is a regression (Used to work in an earlier version of Matplotlib), please
note where it used to work.
It used to work well but I don't remember which version it was.

The best way to run maplotlib in IPython is via the enventloop integration activated with '%matplotlib' in which case you don't need show at all.

Could you elaborate? How do "activate %matplotlib"?

OK I think I activated it just by typing the command in the IPython terminal. But is there a way to include the activation into a python script?

This will happen automatically when in the IPython shell going forward via #6734.
That PR also shows you how to set up the event loop in a script.
