What has been done?
The biggest part of the week was taken again by the refactoring of the existing matplotlib-backend inside MNE-Python. I discussed the changes with my mentors on the Pull-Request and implemented their feedback. Now we are at a point, where we probably can merge this first PR soon to pave the way for the next PR with the integration of the pyqtgraph-backend.
What is coming next?
Now that the refactoring is mostly done I will focus again on the pyqtgraph-backend and its adaption to the parent-class BrowserBase which will be inherited by both backends. Furthermore there need to be new methods to test the pyqtgraph-backend (mouse/keyboard-interaction), which may be solved with pytest-qt.
