Python Matplotlib hangs when asked to plot a second chart (after closing first chart window)

Question

Weird behaviour, I\'m sure it\'s me screwing up, but I\'d like to get to the bottom of what\'s happening:

I am running the following code to create a very simple graph

Answer 1

As posted somewhere above:

Use plt.draw() for all your plots except the last one.

For your last plot, use plt.show()

It's weird, but if you don't use plt.show() in the last one and try plt.draw() instead, you don't see any plots.

Good luck with this!
