I am reading this page about: Scale invariant angle label in Matplotlib

I can follow the example in that page, and reproduce the results. But I wonder if this is already implemented in Matplotlib library itself? or should I create the class myself?

I am using matplotlib 3.4.3 with Python 3.8.10.

CodePudding user response：

No, it is not part of the code-base as of to date.

Looking at the code-base of the version you are using v3.4.3, as well as the one of the most recent version as of to date (v3.5.0b1), AngleAnnotation does not appear.

In the matplotlib git repository the AngleAnnotation class, as sub-class of Arc, occurs only in examples/text_labels_and_annotations/angle_annotation.py which is the example you were reading.
