New user with first post here.
I want a little info box to display at points along the line with more detailed information about the state of the data at that point in time. I have searched and searched the docs. I assume I can’t find it because I don’t know the keywords or matplotlib jargon, but I know it can be done because a similar technology is on every image in the gallery!!! Gallery — Matplotlib 3.4.1 documentation
What do you call this little black box with the white text, and how do I create it. or find it in a tutorial, documentation, or wherever? Thanks!
