Re: Can I remove the continent outline in polar projection plot?

Hi Eddy,

You can make your own copy of $NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_csm.ncl and then modify the following code:

      if(.not.polar_time) then
; Define an array of strings to label the longitude values.
        indexes = ind(plon.gt.0.and.plon.lt.180)
        labels(indexes) = floattoint(plon(indexes)) + "E"
        delete(indexes)

        indexes = ind(plon.gt.180.and.plon.lt.360)
        labels(indexes) = floattoint(360-plon(indexes)) + "W"
        delete(indexes)

        indexes = ind(plon.eq.0.or.plon.eq.180)
        labels(indexes) = floattoint(plon(indexes))
        delete(indexes)
      else
;

to be something like:

      if(.not.polar_time) then
; Define an array of strings to label the longitude values.
        labels(indexes) = floattoint(plon(indexes)) + ""
      else
. . .
