Variable sized y-axes in EEG plots

Hi! This is a bit of a beginner question. I’ve seen various packages which plot EEGs stacking traces with varying sizes on the y-axis. Here’s an example:

Currently, I can only figure out how to to use the .plot(…)e.g. on raw data to produce where each trace is given the same amount of space. The only options are to either normalize everything to 1, clamp the values or overdraw with neighbouring traces.

Is this feature not yet implemented or did I just miss it? Is it the sort of thing I should make an issue + PR for?

Currently, you can set different scalings for different sensor types (e.g. EEG versus EOG), but not for different channels of the same type. We could add this to MNE-Python if there is a good use case for it. In what kind of scenarios would this be useful?
