mne.viz.plot_raw_psd¶

mne.viz.plot_raw_psd(raw, tmin=0.0, tmax=inf, fmin=0, fmax=inf, proj=False, n_fft=2048, picks=None, ax=None, color='black', area_mode='std', area_alpha=0.33, n_overlap=0, dB=True, show=True, n_jobs=1, verbose=None)¶

Plot the power spectral density across channels

Parameters:

raw : instance of io.Raw The raw instance to use. tmin : float Start time for calculations. tmax : float End time for calculations. fmin : float Start frequency to consider. fmax : float End frequency to consider. proj : bool Apply projection. n_fft : int Number of points to use in Welch FFT calculations. picks : array-like of int | None List of channels to use. Cannot be None if ax is supplied. If both picks and ax are None, separate subplots will be created for each standard channel type (mag, grad, and eeg). ax : instance of matplotlib Axes | None Axes to plot into. If None, axes will be created. color : str | tuple A matplotlib-compatible color to use. area_mode : str | None Mode for plotting area. If ‘std’, the mean +/- 1 STD (across channels) will be plotted. If ‘range’, the min and max (across channels) will be plotted. Bad channels will be excluded from these calculations. If None, no area will be plotted. area_alpha : float Alpha for the area. n_overlap : int The number of points of overlap between blocks. The default value is 0 (no overlap). dB : bool If True, transform data to decibels. show : bool Show figure if True. n_jobs : int Number of jobs to run in parallel. verbose : bool, str, int, or None If not None, override default verbose level (see mne.verbose).

Returns:

fig : instance of matplotlib figure Figure with frequency spectra of the data channels.
