X Title: Attach a FigureCanvasBase by default to Figures. by anntzer · Pull Request #12450 · matplotlib/matplotlib

Description: This is particularly useful for headless cases, where one just wants to take advantage of print_figure, which is defined on the base class. For example, one can now do for : figure = Figure() # do some plotting figure.savefig(...) and let figure get gc'd at the next loop iteration; a pyplot-based solution would instead have to explicitly close() the figure or reuse it after clf()'ing it. Also simplifies various places in the codebase where we had to handle the case of .canvas = None previously. xref #11657, #12447. PR Summary PR Checklist Has Pytest style unit tests Code is Flake 8 compliant New features are documented, with examples if plot related Documentation is sphinx and numpydoc compliant Added an entry to doc/users/next_whats_new/ if major new feature (follow instructions in README.rst there) Documented in doc/api/api_changes.rst if API changed in a backward-incompatible way
