I used the first two traces for this study. For plotting the time series, I first read the data using the read function from Obspy and then plot the "data" and "times" methods avilable for the Trace object.35 and single what to doSolved it, with help from this link.It doesn't show decibels yet but the primary issue was getting the colorbar: from obspy.imaging.spectrogram import spectrogram fig = plt.figure() ax1 = fig.add_axes([0.1, 0.75, 0.7, 0.2]) #[left bottom width height] ax2 = fig.add_axes([0.1, 0.1, 0.7, 0.60], sharex=ax1) ax3 = fig.add_axes([0.83, 0.1, 0.03, 0.6]) #make time vector t = np.arange(spl1[0].stats ...
