mne.viz.plot_evoked_field(evoked, surf_maps, time=None, time_label='t = %0.0f ms', n_jobs=1, fig=None, vmax=None, n_contours=21, verbose=None)[source]

Plot MEG/EEG fields on head surface and helmet in 3D.

evokedinstance of mne.Evoked

The evoked object.


The surface mapping information obtained with make_field_map.

timefloat | None

The time point at which the field map shall be displayed. If None, the average peak latency (across sensor types) is used.

time_labelstr | None

How to print info about the time instant visualized.


The number of jobs to run in parallel (default 1). Requires the joblib package.

figinstance of mayavi.core.api.Scene | None

If None (default), a new figure will be created, otherwise it will plot into the given figure.

New in version 0.20.

vmaxfloat | None

Maximum intensity. Can be None to use the max(abs(data)).

New in version 0.21.


The number of contours.

New in version 0.21.

verbosebool, str, int, or None
