Plot estimated latent sources given the unmixing matrix.
Typical usecases:
plot evolution of latent sources over time based on (Raw input)
plot latent source around event related time windows (Epochs input)
plot time-locking in ICA space (Evoked input)
mne.preprocessing.ICAThe ICA solution.
mne.io.Raw, mne.Epochs, mne.EvokedThe object to plot the sources from.
int | list of int | slice | NoneIndices of the independent components (ICs) to visualize.
If an integer, represents the index of the IC to pick.
Multiple ICs can be selected using a list of int or a slice.
The indices are 0-indexed, so picks=1 will
pick the second IC: ICA001. None (default) will pick all sources in the order fitted.
float | int | NoneIf inst is a Raw or an Evoked object, the first and
last time point (in seconds) of the data to plot. If inst is a
Raw object, start=None and stop=None will be
translated into start=0. and stop=3., respectively. For
Evoked, None refers to the beginning and end of the evoked
signal. If inst is an Epochs object, specifies the index of
the first and last epoch to show.
str | NoneThe window title. If None a default is provided.
Show figure if True.
Whether to halt program execution until the figure is closed. Useful for interactive selection of components in raw and epoch plotter. For evoked, this parameter has no effect. Defaults to False.
If True, show time axis relative to the raw.first_samp.
Whether to show scrollbars when the plot is initialized. Can be toggled
after initialization by pressing z (“zen mode”) while the plot
window is focused. Default is True.
New in version 0.19.0.
Style of time labels on the horizontal axis. If 'float', labels will be
number of seconds from the start of the recording. If 'clock',
labels will show “clock time” (hours/minutes/seconds) inferred from
raw.info['meas_date']. Default is 'float'.
New in version 0.24.
strWhether to load all data (not just the visible portion) into RAM and
apply preprocessing (e.g., projectors) to the full data array in a separate
processor thread, instead of window-by-window during scrolling. The default
None uses the MNE_BROWSER_PRECOMPUTE variable, which defaults to
'auto'. 'auto' compares available RAM space to the expected size of
the precomputed data, and precomputes only if enough RAM is available.
This is only used with the Qt backend.
New in version 0.24.
Changed in version 1.0: Support for the MNE_BROWSER_PRECOMPUTE config variable.
NoneWhether to use OpenGL when rendering the plot (requires pyopengl).
May increase performance, but effect is dependent on system CPU and
graphics hardware. Only works if using the Qt backend. Default is
None, which will use False unless the user configuration variable
MNE_BROWSER_USE_OPENGL is set to 'true',
see mne.set_config().
New in version 0.24.
str | path-likeCan be “auto”, “light”, or “dark” or a path-like to a
custom stylesheet. For Dark-Mode and automatic Dark-Mode-Detection,
qdarkstyle and
darkdetect,
respectively, are required. If None (default), the config option MNE_BROWSER_THEME will be used,
defaulting to “auto” if it’s not found.
Only supported by the 'qt' backend.
New in version 1.0.
str | NoneCan be “channels”, “empty”, or “hidden” to set the overview bar mode
for the 'qt' backend. If None (default), the config option
MNE_BROWSER_OVERVIEW_MODE will be used, defaulting to “channels”
if it’s not found.
New in version 1.1.
matplotlib.figure.Figure | mne_qt_browser.figure.MNEQtBrowserBrowser instance.
Notes
For raw and epoch instances, it is possible to select components for
exclusion by clicking on the line. The selected components are added to
ica.exclude on close.
New in version 0.10.0.
