obspy.signal.spectral_estimation.PPSD.plot_spectrogram

PPSD.plot_spectrogram(cmap=<matplotlib.colors.LinearSegmentedColormap object>, clim=None, grid=True, filename=None, show=True)[source]

Plot the temporal evolution of the PSD in a spectrogram-like plot.

Note

For example plots see the Obspy Gallery.

Parameters

  • cmap (matplotlib.colors.Colormap) – Specify a custom colormap instance. If not specified, then the default ObsPy sequential colormap is used.

  • clim (list) – Minimum/maximum dB values for lower/upper end of colormap. Specified as type float or None for no clipping on one end of the scale (e.g. clim=[-150, None] for a lower limit of -150 dB and no clipping on upper end).

  • grid (bool) – Enable/disable grid in histogram plot.

  • filename (str) – Name of output file

  • show (bool) – Enable/disable immediately showing the plot.
