class eelbrain.plot.SensorMap(sensors, labels='name', proj='default', size=1, color='k', marker='.', mark=None, head_radius=None, head_pos=0.0, connectivity=False, margins=None, **kwargs)

Plot sensor positions in 2 dimensions

  • sensors (Sensor | NDVar) – The Sensor dimension, or an NDVar with a sensor dimension.

  • labels ('none' | 'index' | 'name' | 'fullname') – Content of the labels. For ‘name’, any prefix common to all names is removed; with ‘fullname’, the full name is shown.

  • proj – Transform to apply to 3 dimensional sensor coordinates for plotting locations in a plane

  • size (scalar) – Size for the sensor markers.

  • color (matplotlib color) – Color for the sensor markers.

  • marker (str) – Marker for the sensor positions.

  • mark (None | list of int) – List of sensor indices to mark.

  • head_radius (scalar | tuple | True) – Radius of the head outline drawn over sensors (on sensor plots with normalized positions, 0.45 is the outline of the topomap); 0 to plot no outline; tuple for separate (right, anterior) radius. True to be equal to plot.Topomap with method="mne". The default is determined automatically.

  • head_pos (scalar) – Head outline position along the anterior axis (0 is the center, 0.5 is the top end of the plot).

  • connectivity (bool) – Show sensor connectivity (default False).

  • .. – Also accepts General layout parameters.
