Dear Mary,
load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_code.ncl"
load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_csm.ncl"
wks = gsn_open_wks("ps","test_grid")
res = True
res@mpProjection = "Mercator"
res@mpLimitMode = "LatLon"
res@mpMinLonF = 11.
res@mpMaxLonF = 12.
res@mpMinLatF = 33.
res@mpMaxLatF = 34.
;res@mpMinLatF = 33.2667
;res@mpMaxLatF = 33.9333
res@pmTickMarkDisplayMode = "Always"
res@mpGridAndLimbOn = True
res@mpGridLonSpacingF = 1./60.
res@mpGridLatSpacingF = 1./60.
res@tmXTOn = True
res@tmYROn = True
plot = gsn_csm_map(wks,res)
Everything is fine, thank you.
However, if we uncomment two lines (mpMinLatF = 33.2667 and mpMaxLatF =
33.9333) then the vertical(!) grid lines disappear.
