Re: poly marker

You have to draw the plot after you add the polymarker(s):

   res@gsnDraw = False
   plot = gsn_csm_contour_map_ce(wks, x, res)

   mkres = True
   mkres@gsMarkerIndex = 17 ; Filled circle
   mkres@gsMarkerSizeF = 0.50

   gsn_polymarker(wks,plot,lon,lat,mkres)
   draw(plot)
   frame(wks) ; Now advance the frame.

end

See the polymarker/polyline examples here:
