Remove annotation

the annotation does not disappear when the mouse leaves the figure or axis so quickly

By default, this is the expected behavior. Annotations appear when you click and do not move or disappear until you dismiss them (right click to dismiss).

Do you mean with hover=True? If so, yes, if you move the mouse quickly enough, it will remain. It will disappear again as soon as you move your mouse back over the figure. There's not much that can be done to avoid this. mpldatacursor deliberately rate-limits its callbacks to avoid CPU usage issues. That means that if you manage to move the mouse out of the figure in less than the callback rate-limit interval, the popup will remain. If you'd like, that interval can be made configurable to lessen the frequency that this occurs at, but decreasing the callback interval will increase CPU usage.
