Hi,
I am trying to read signal of two earthquakes in SAC and plot the spectrograms. I need to compare the power density spectrum. How can I make the range of color scale on pds for both signals to be the same (as we do for Ylim e.g.)?


qdp off
Ylim -2e5 2e5
cut 55 80

r 2018-12-24-1324.SAC
spectrogram window 2 slice .2 method pds order 100 ymin 0 ymax 50 noscaling
pause


r 2019-02-06-1648.SAC
spectrogram window 2 slice .2 method pds order 100 ymin 0 ymax 50 noscaling

Best regards,
Zoya
