Something like this can be achieved with `Axes.set_autoscale(False)`, but I would like to keep auto-scaling on, and disable it for a particular feature. As far as I understand this is how collections work, which `Axes.scatter` uses in the background.\r\n\r\n**Context:** this feature will allow GeoPandas to consistently plot line, polygon (using `add_collection()`) and point data (using `scatter()`) as contextual data not affecting axes limits (see geopandas/geopandas#2602). Down the line it will benefit a small library I am developing ([hyoga](https://hyoga.readthedocs.io)), to plot gridded data with xarray, and geographic data for context with geopandas.\n\n### Proposed solution\n\nI noticed that `add_collection` has an `autolim` keyword that defaults to `True`. As opposed to completely disabling auto-scaling, setting `autolim=False` simply skips updating the axes data limits for this particular collection, meaning auto-scaling stays on, but ignores it (if I read this correctly). I propose to propagate the `autolim` keyword argument to `Axes.scatter` and pass it to `add_collection` here:\r\n\r\nhttps://github.com/matplotlib/matplotlib/blob/9d8fde258d66168f20800155af614c8ca0bb8e24/lib/matplotlib/axes/_axes.py#L4680-L4681\r\n\r\nThis would allow something like:\r\n\r\n```python\r\nax.scatter(x_subject, y_subject)  # default to autolim=True, update limits\r\nax.scatter(x_context, y_context, autolim=False)  # don't update limits\r\nax.plot(something_else)  # update limits disregarding {x,y}_context\r\n```\r\nI am happy to open a PR if this makes sense.","author":{"url":"https://github.com/juseg","@type":"Person","name":"juseg"},"datePublished":"2022-11-10T10:36:07.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":2},"url":"https://github.com/24416/matplotlib/issues/24416"}
