Description of the problem

Where OPM systems (e.g. Cerca) have the same sensor position but different sensor orientations (X,Y,Z) this causes issues when plotting topoplots.

Steps to reproduce

For example...

ica.plot_components()

Link to data

No response

Expected results

Ideally topoplots should be produced using data projected though only one axis, rather than splitting up the data beforehand. To be more explicit - ICA should be run on all axes but topoplots should be produced using (for example) the Z-axis

Actual results

Error - ValueError: The following electrodes have overlapping positions, which causes problems during visualization:
