.Th YLIM
.S2 SUMMARY:
Define plot limits for y-axis

YLIM [ALL | OFF | Scale min max ]

.S2 INPUT:
.BR
ALL           : Plot all traces in the current window to the same scale
.BR
OFF           : Each trace is autoscaled
.BR
Scale min max : User specified minimum and maximum values
.BR

.S2 DESCRIPTION:
This option permits all traces on a screen to be plotted using the same 
scale so that the relative differences in amplitude are obvious. Otherwise
each trace is plotted with its own scale.
.sp
The min max in scale can be in scientific notation, e.g.,
.BR
     YLIM SCALE 1.0e-6 2.0e-5
.BR
.S2 EXAMPLES:

.S2 "SAC COMPATIBILITY:"
Sac permits a PM v to set +- v. It also permits setting the scaling of 
individual traces in a multitrace plot. GSAC does not permit either.

Note this command only affects the time series plots using the command plot1.
It does not affect the spectra plot using the command plotsp or the record
section plot  prs.
.S2 DEFAULT:
YLIM OFF
