Updating A Plot In Python's Matplotlib

I'm trying to plot streaming data in matplotlib. I can update the plot using interactive mode and the set_ydata function. It animates and everything looks good until the loop ends.

Solution 1:

It works well for me with mac_osx backend from Jupyter notebook in python 3.4.

Maybe you want to add plt.close() at the end to keep things tidy and prevent a hang up?
