Hi Boyin,

You can use the 4-argument form of the LEVELS qualifier -- see the User's
Guide, Ch6 Sec8.1.1:
http://ferret.wrc.noaa.gov/Ferret/Documentation/Users_Guide/current/Chapter6_Customizing_Plots.htm#Chapter6-Contouring

This has the form
   /LEVELS=(lo, hi, delta, ndigits)
where ndigits is the number of decimal places (-1=integer, -3=no label).

EXAMPLE:
  use coads_climatology
  set region t
  fill/line/key/lev=(-1,1,.2,1) sst[l=1]-sst[l=@ave]

Cheers,

Andrew
