PPSD.plot_spectrogram(cmap=<matplotlib.colors.LinearSegmentedColormap object at 0x43166aac>, 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.
