heiko,
you can do this, but you need to do it explicitly.
;================================================;
; mptick_6.ncl
;================================================;
load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_code.ncl"
load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_csm.ncl"
; ================================================;
begin
wks = gsn_open_wks("ps","mptick") ; open a ps file
res = True
res@tmXBMode = "Explicit"
res@tmXBValues = (/-180, -90, 0, 90, 180/)
res@tmXBLabels = (/"180","90W","EQ","90E","180"/)
plot = gsn_csm_map_ce(wks,False) ; draw global map
end
in this case we tried changing the 0 label to "EQ", but in your case
you can put in grid cell numbers. It requires that you
know the lat/lon "Value" of each of the grid cell numbers that
you want.
