Currently `Lines`, `Patches` and `AxesImage` obligatorily participate https://github.com/matplotlib/matplotlib/blob/a046ee3febac399869c3eb6b15b8e669e37058ee/lib/matplotlib/axes/_base.py#L2459-L2483 and collections may optionally participate, but only when they are added https://github.com/matplotlib/matplotlib/blob/a046ee3febac399869c3eb6b15b8e669e37058ee/lib/matplotlib/axes/_base.py#L2260-L2273 \n\n### Proposed solution\n\nThe proposed solution is to:\r\n\r\n - move the `_update_line_limits` and friends to the respective Artists\r\n - add an analogous method to the base `Artist` (probably defaulting to failure)\r\n - add a \"I would like to particpate in autolimiting!\" flag to base `Artist`\r\n - in `relim` look at the flag and call the newly generalized method above on any artists that opt-in\r\n\r\n\r\nThis will involved a little bit of public API (how to set the state to opt-in) and a bunch of private API (what should the signature of the method be).","author":{"url":"https://github.com/tacaswell","@type":"Person","name":"tacaswell"},"datePublished":"2023-02-02T22:21:58.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":4},"url":"https://github.com/25139/matplotlib/issues/25139"}
