[SAC-HELP] sonogram and spectrogram problem_2nd email

[George Helffrich]

Dear List -

	I suspect this is due to the lack of TrueColor support in the X 
support in SAC2000.  If correct, you'll get the same result any time 
you use color -- is this true?  Experiment and see.

	You can avoid triggering the color problem by plotting in black and 
white using 'spectrogram gray' or 'spectrogram xyz' and then contouring 
the resulting xyz file.

	You might be able to configure your X server not to provide a 
TrueColor screen choice.  This is a black art, not for novices, but you 
might have some success by that route.  (I can provide no advice -- X 
installations vary widely, and you'll have to consult your own 
distribution manuals.)

	If you have access to a Mac, you could also use MacSAC which has 
TrueColor support and which also has a functioning spectrogram command.
