If you want to learn more about matplotlib animations you should really follow this tutorial. It explains in great length how to create animated plots. Note: Creating animated plots require ffmpeg or mencoder to be installed. Here is a version of his first example changed to work with your scatterplot. # First import everthing you … Read more
A couple of notes: First off, the reason that things become progressively slower is that you’re drawing more and more and more overlapping lines in the same position. A quick fix is to clear the plot each time: import numpy as np import matplotlib.pyplot as plt x = np.linspace(0, 10, 100) y = np.sin(x) plt.figure() … Read more
Here is a FuncAnimation example which I modified to pause on mouse clicks. Since the animation is driven by a generator function, simData, when the global variable pause is True, yielding the same data makes the animation appear paused. The value of paused is toggled by setting up an event callback: def onClick(event): global pause … Read more
You’re very close, but there’s one mistake – init and animate should return iterables containing the artists that are being animated. That’s why in Jake’s version they return line, (which is actually a tuple) rather than line (which is a single line object). Sadly the docs are not clear on this! You can fix your … Read more
