RE: [ncl-talk] How to put marker above the Geophysical Line

Hi, I'm sorry that it took up you much time. I set these resource, but it does not work for procedure gsn_text_ndc. mpres@mpFillOn = False
   mpres@mpGridAndLimbOn = True
   mpres@mpGridAndLimbDrawOrder = "Draw"
   mpres@mpGridSpacingF = 10.
   mpres@mpGridLineColor = "gray"
   mpres@mpGridLineDashPattern = 16
   mpres@mpOutlineBoundarySets = "National"
   mpres@mpOutlineDrawOrder = "Draw"
   mpres@mpGeophysicalLineColor = "gray"
   mpres@mpGeophysicalLineThicknessF = .5
   mpres@mpNationalLineColor = "gray" You can look up and modify my scripts:/glade/home/zqjiang/scripts/verif2/mpsite_stat_f06.ncl/glade/home/zqjiang/scripts/verif2/submit.csh
After modifying mpsite_stat_f06.ncl, ./submit.csh
