This video is the clearest explanation of FuncAnimation that I’ve seen thank you so much! I’d love you if you made another video going into how to make 3D animations with Matplotlib as well!

[@YounesLab]

I appreciate it! Thank you I did somewhat of a simple 3d animation with the lorenz attractor you can check it out: kzbin.info/www/bejne/fZWxm4eAj9OHo68&ab_channel=YounesLab And I am currently working on the 3 body problem so be sure to stick around!

This is absolutely amazing, thank you!!!

Hi, How can you make legend and label update with each frame in these examples. Say, I just want to make the frame number appear in text as the animation happens.

[@YounesLab]

In order to update text within your animation, you have to set the blit mode to false `blit=False` and then specify within the update function a line that update the title for example: fig, axis = plt.subplots() animated_bridge, = axis.plot([], [], color='blue') # ',' is used because axis.plot returns an array axis.set_xlim([0, L]) axis.set_ylim([-10, 10]) axis.set_title(f"Frame: {0} / {len(time_points)}") # Initial title def update(frame): print(frame) animated_bridge.set_data(space_points, u[frame]) # Updating the data across [frame] axis.set_title(f"Frame: {frame} / {len(time_points)}") return animated_bridge

Amazing video! Any tips on make the gif faster ? I got 4000 frames and it run soooo slow. Can python render it every 10 frames so it will run faster? Thanks for the video!

[@YounesLab]

Thank you for your feedback @aliffahrizi 😄 There actually is a trick to make the animation go faster! Here the trick: (I discovered it recently 😅) The main idea is to tweak the `frames` argument within the `FuncAnimation` function: - Setting `frames = len(t_points)` will render every frame (slower) you can also set it to an array `frames = range(1, len(t_points))`. Now both of these are equivalent, meaning in both cases we are considereing all the frames. - However we can also do something like `frames = range(1, len(t_points), n)` saying we want to render a portion of it, skipping every `n` frame. This should make the animation n-times faster! Note: The classical way the range function works: range object range(start, stop, step)

Thank you! This is very few tutorials on this on youtube. btw, isn't that supposed to be 'axes' not 'axis' (fig, axis = ...)?

[@YounesLab]

True, 'axis' refers to a single object, where 'axes' refer to multiple ones within one figure. Thank you for pointing this one out! :)
