Dear All -
This is somewhat complicated, but, briefly, you can use the SPECTROGRAM XYZ option (which makes the spectrogram into 3D data), and then plot the spectrogram and the color scale in two separate viewports on the same display. See the comments for how it works.
fg seismogram ;* Test data
spectrogram xyz; write /tmp/hold.xyz
* Save bounds of spectrogram
setbb smin &1,depmin&
setbb smax &1,depmax&
* Make 3D grid increasing from min to max value in spectrogram
* This becomes the color scale when turned into a SAC xyz file
funcgen npts 5 delta 1 line 0 %smax%; w /tmp/scale.sac ;* highest grid value
do i = 1, 99
funcgen npts 5 delta 1 line 0 ( %smax% - ($i$ * (%smax% - %smin%) / 100 ) )
merge checktimes off /tmp/scale.sac ;* next lower grid value
write /tmp/scale.sac
enddo
ch iftype ixyz nxsize 5 xminimum 0 xmaximum 4 nysize 100 yminimum 0 ymaximum 100
w /tmp/scale.sac
* Make spectrogram and color scale plot
beginframe
xvp 0.1 0.7; read /tmp/hold.xyz; grayscale color; xvp previous ;* spectrogram
axis off bottom; ticks off top bottom; fileid off
xvp 0.8 0.9; read /tmp/scale.sac; grayscale color; xvp previous;* color scale
fileid previous; ticks previous; axis previous
endframe

Hi.
Will someone know how to move the scale of colors, to any position, that comes out mounted on the "y" axis of the spectrograms? I want to move it to a position outside the graph to avoid confusing the scale referred to the "y" axis with the color scale. Thank you
