Annotating Plots — Matplotlib 3.5.2 documentation Using multiple coordinate systems and axis types#. You can specify the xypoint and the xytext in different positions and coordinate systems, and optionally turn on a connecting line and mark the point with a marker. Annotations work on polar axes too. In the example below, the xy point is in native coordinates (xycoords defaults to 'data'). For a polar axes, this is in (theta, radius) space.
