When i first got into this I was essentially doing:\r\n```python\r\nfor t in range(timepoints):\r\n    ax.imshow(data[t])\r\n```\r\nwhich is bad news for performance. I fortunately had someone around to tell me to use `set_data` but lacking that I think it would have taken me a lot longer to figure out. \r\n\r\nHowever, even after figuring that out it's not all smooth sailing. I was tripped up for quite awhile on how to animate a scatter plot as it uses `set_offsets` instead of `set_data`. There can also be other complications see for example https://github.com/matplotlib/matplotlib/issues/18401. \r\n\r\n\r\n### Suggested Improvement\r\nInclude a reference style example in the animation section of the gallery that goes over how to animate all the possible animatable artists (`set_data`, `set_offsets`, etc...). Or at least all of the artists that get returned from pyplot functions. Ideally the example would use the artists created from pyplot(or equivalent `ax`) functions as this is how I imagine most people will create the artists for their animations.\r\n\r\nFor reference I brought this up on gitter, but gitter just crashed :(\r\n\r\n**Matplotlib version**\r\n  * Matplotlib documentation version: any","author":{"url":"https://github.com/ianhi","@type":"Person","name":"ianhi"},"datePublished":"2021-02-16T01:05:26.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":5},"url":"https://github.com/19520/matplotlib/issues/19520"}
