"The only thing worse than no comments are outdated comments"
IIRC, "block" was long removed from matplotlib. If you want non-blocking
behavior, just call "plt.ion()" to turn interactivity on. There are other
approaches to this problem that you would want to examine if you were truly
embedding into an application, but in the most simple cases, just turning
interactivity on should do the trick.
