Maybe I’m missing something in this manual, but I’d like to know why not all connectivities are plotted by this function, although the connectivity of all channel combinations are fed to this plot function.
the function is hard-coded to only show the strongest 20 connections:
Probably that should be a parameter of the plot_sensors_connectivity function, that users could specify. Feel free to open a feature request on the MNE-Connectivity GitHub repo about it.
