Re: [ferret_users] Title at the top of the plot

It seems much simpler to use LABELS to put whatever text you want  
wherever you want it.

Here's a little script to determine the center and appropriate  
distance above a plotbox for titles:

-------
\can mode verify
! get the current value of the PPLUS axis lengths.
let xxlen = ($ppl$xlen) ; let yylen = ($ppl$ylen)
let ctr = xxlen/2; let toplab = yylen+.9; let toplab2 = yylen+.4
say xxlen, yylen, xxlen/yylen = `xxlen`, `yylen`, `xxlen/yylen`
set mode/last verify
-------

Put this in your path; I call it "getlens.go". It defines the center  
in the x-direction, and two useful heights above the plot box in the  
y-direction (in no-user units, independent of the particular values  
being plotted). Then:

set vi ....
plot/nolab .....    ! omit the title and labels
! plot/tit=" " ....    ! if the automatic labels are desired, but  
excluding the title
go getlens.go
label/nou `ctr` `toplab` 0 0 .25 Main title text
label/nou `ctr` `toplab2` 0 0 .16 Secondary title text

Or, if you want to put the automatic title in a different place:
First make a dummy plot (which will have the title at the bottom).  
This will define the symbol ($labtit) which contains the automatic  
title. Then:

plot/nolab ....    ! real plot omitting the title
label/nou `ctr` `toplab` 0 0 .25 ($labtit)    ! place the title at  
the top
