Plot evoked data

Left click to a line shows the channel name. Selecting an area by clicking and holding left mouse button plots a topographic map of the painted area.

Note: If bad channels are not excluded they are shown in red.


evoked : instance of Evoked

The evoked data

picks : array-like of int | None

The indices of channels to plot. If None show all.

exclude : list of str | ‘bads’

Channels names to exclude from being shown. If ‘bads’, the bad channels are excluded.

unit : bool

Scale plot with channel (SI) unit.

show : bool

Show figure if True.

ylim : dict | None

ylim for plots. e.g. ylim = dict(eeg=[-200e-6, 200e6]) Valid keys are eeg, mag, grad, misc. If None, the ylim parameter for each channel equals the pyplot default.

xlim : ‘tight’ | tuple | None

xlim for plots.

proj : bool | ‘interactive’

If true SSP projections are applied before display. If ‘interactive’, a check box for reversible selection of SSP projection vectors will be shown.

hline : list of floats | None

The values at which to show an horizontal line.

units : dict | None

The units of the channel types used for axes lables. If None, defaults to dict(eeg=’uV’, grad=’fT/cm’, mag=’fT’).

scalings : dict | None

The scalings of the channel types to be applied for plotting. If None,` defaults to dict(eeg=1e6, grad=1e13, mag=1e15).

titles : dict | None

The titles associated with the channels. If None, defaults to dict(eeg=’EEG’, grad=’Gradiometers’, mag=’Magnetometers’).

axes : instance of Axis | list | None

The axes to plot to. If list, the list must be a list of Axes of the same length as the number of channel types. If instance of Axes, there must be only one channel type plotted.

gfp : bool | ‘only’

Plot GFP in green if True or “only”. If “only”, then the individual channel traces will not be shown.

window_title : str | None

The title to put at the top of the figure.

spatial_colors : bool

If True, the lines are color coded by mapping physical sensor coordinates into color values. Spatially similar channels will have similar colors. Bad channels will be dotted. If False, the good channels are plotted black and bad channels red. Defaults to False.
