mne.viz.plot_head_positions#

mne.viz.plot_head_positions(pos, mode='traces', cmap='viridis', direction='z', *, show=True, destination=None, info=None, color='k', axes=None, totals=False)[source]#

Plot head positions.

Parameters:
posndarray, shape (n_pos, 10) | list of ndarray

The head position data. Can also be a list to treat as a concatenation of runs.

modestr

Can be ‘traces’ (default) to show position and quaternion traces, or ‘field’ to show the position as a vector field over time.

cmapcolormap

Colormap to use for the trace plot, default is “viridis”.

directionstr

Can be any combination of “x”, “y”, or “z” (default: “z”) to show directional axes in “field” mode.

showbool

Show figure if True. Defaults to True.

destinationpath-like | array_like, shape (3,) | instance of Transform | None

The destination location for the head. See mne.preprocessing.maxwell_filter() for details.

New in v0.16.

infomne.Info | None

The mne.Info object with information about the sensors and methods of measurement. If provided, will be used to show the destination position when destination is None, and for showing the MEG sensors.

New in v0.16.

colorcolor object

The color to use for lines in mode == 'traces' and quiver arrows in mode == 'field'.

New in v0.16.

axesarray_like, shape (3, 2) or (4, 2)

The matplotlib axes to use.

New in v0.16.

Changed in version 1.8: Added support for making use of this argument when mode="field".

totalsbool

If True and in traces mode, show the total distance and angle in a fourth row.

New in v1.9.

Returns:
figinstance of matplotlib.figure.Figure

The figure.
