Hi Ferret users,

It seems that the NOLABEL qualifier sometimes "leaves" labels behind,
which shows up later:

  NOAA/PMEL TMAP
  FERRET v6.94
  Darwin 14.1.0 - 02/26/15
  1-Apr-16 17:38

yes? set data levitus_climatology
yes? let allmissing = 0/0 + temp
yes? shade/nolabel/y=0 allmissing
yes? polygon/palette=gray/ov {50,180,180,50},{4000,4000,1000,1000}

See the label "ALLMISSING" near the lower-left corner?  It doesn't
show up when you add NOLABEL to the polygon command, but it's not
intuitive.

Cheers,

Ryo
