transfreq.viz.plot_psds

transfreq.viz.plot_psds(psds, freqs, average=True, showfig=True, ax=None)

Plot normalised power spectrum

Parameters:

psds: array, shape (N_sensors, N_freqs)

power spectral matrix

freqs: array, shape (N_freqs,)

frequncies at which the psds is computed

average: bool (default True)

if True the power spectrum is averaged over the channels. If False the power spectrum of each channel is dislayed

showfig: bool (default True)

if True figure will be showed, if False figure will not be showed

ax: instance of Axes | None

Axes to plot into. If None, axes will be created.

Returns:

fig: instance of Figure

Figure representing rest and task power spectra profiles and the transition frequencycomputed with Klimesch’s method
