Grouping EEG channels when viewing

  • MNE version: 1.9.0
  • operating system: macOS 15.5

I’m simply trying to group electrodes as they would be in a usual clinical montage, rather than all the channels being equally spaced. See attached picture (does not have to be re-montaged to bipolar but even if it is in bipolar I’d like to be able to gorup)

raw = mne.io.read_raw_edf(‘fname.EDF’, preload=True)
raw.plot()

Unfortunately, this is currently not possible, but it would be a really nice addition!

I’d consider it a worthwhile enhancement to enable this. Probably easiest would be to allow the order param to take a list-of-lists, and insert the spacing between the groups of channels in each sublist. Feel free to open a pull request to implement this, or if you’re not comfortable contributing code, open a feature request on our GitHub repository so that someone else can hopefully implement it.
