This is a collection of scripts taking baby steps* towards building an interactive tool to associate topological features - in particular loops/voids - with some reasonable subset of the data which is "responsible" (aka, a generator). Here the topological features are represented by birth/death pairs.
*Yes, I'm aware of how git works, but I prefer to have hard checkpoints for increasingly complex functionality.
- numpy (I'm on version 1.18.3 but earlier versions are probably fine)
- matplotlib (I'm on version 3.0.3)
- cechmate (version 0.0.8) and phat (version ???). These were set up when I did a
pip installof scikit-tda, but you may need to install them explicitly. - pybind11
Just run mpl_generator_interactivity_ex0.py in ipython or a jupyter notebook. The main class powering the most up to date version is in int_gen.py. The rest of the scripts are my baby steps in building up from the sample code in https://matplotlib.org/3.1.1/users/event_handling.html#object-picking towards the specific functionality I want.
