Re: plotting diferent ranges

[Ansley Manke <ansley.b.manke@xxxxxxxx>]

Hi Tony,
I have just a couple more suggestions to add to Mick's answer.  If you
know ahead of time what a good range for all your data will be, you can say

PLOT/VLIMITS=lo:hi  T1
(then commands to read the second file, then)
PLOT/OVER/THICK T2   ! will use the same vertical axis, of course.

Where lo and hi are the limits that you want to set.

You can also read in all the data, and plot the variables with a single
PLOT command, and then Ferret will determine a range of data which
fits them all

file/form=free/g=grd/var=height,A,B,var dat1.dat
file/form=free/g=grd/var=height,A,B,var dat2.dat
file/form=free/g=grd/var=height,A,B,var dat3.dat

PLOT/nolab var[d=1], var[d=2], var[d=3]

or with named data sets,

PLOT/nolab var[d=dat1], var[d=dat2], var[d=dat3]

(Note, it is not a good idea to name your variable T, as this is
the name of the pseudo-variable for time on an axis.)
