Re: [ferret_users] change contour line thickness

[Jaison Kurian <jaison@xxxxxxxxxxxxxxxxxx>]

Hi Jammal,
            The answer to your question is, use /LEVELS qualifier with its
additional option "LINE", as /LEVELS="(lo,hi,delta) line(lo,hi,delta,1)".
See the examples given below (specifically, case 3). See User Manual,
Ch6 Sec8.1.1. to know more about /LEVELS qualifier. Use Ferret Manual and
mail archives ("Search the Archives" option is available at
http://ferret.pmel.noaa.gov/Ferret/Mail_Archives/ferret_mail_archives.html)
as first steps to solve any of your Ferret problem. I am pretty sure that 
you will find answer to most of your questions in this way.

! How to change the default thin/thick/dash/color scheme of contours? 
! 
! Let us make a dummy variable
!
     let var = (i[i=1:120]/100)^2+(j[j=1:120]/100)^2-1
!
!1. Default plot
!
     contour/lev="(-.8,.8,.2)"  var 
     pause 
!
!2. Thin continuous 0-line
!
     contour/lev="(-.8,.8,.2) line(0)" var
     pause
!
!3. All thin continuos lines
!
     contour/lev="(-.8,.8,.2) line(-.8,.8,.2,1)" var
     pause
!
!4. Thick continous -ve lines
