You might find that plt.pause(1) is helpful. See pylab_examples/animation_demo.py. Also, it sounds like running via ipython, if possible, would make things easier for you; it takes care of all sorts of difficulties with interactivity. And it's wonderfully helpful in other ways as well. > > I try to use block=False but this makes that the plot is not shown. I > want to change my original script as little as possible.

I'm sure that one or more of the suggestions above can lead to a simple solution.
