Hi~

I'm trying to add a polymarker at 116E,40N to the wrf_overlay plot. But the
marker came out to be the wrong place It lies not at the exact 116E,40N as
indicated by the axis value.(see the plot )

I'm wondering why this happened. Thanks~

NCL Script( in fraction):

 pmres=res
      pmres@gsMarkerIndex = 12
      pmres@gsMarkerColor = "red"
      pmres@gsMarkerSizeF = 0.02
      pmres@gsMarkerThicknessF=2.0
      pltres@FramePlot= False
    ; MAKE PLOTS
      plot =
wrf_map_overlays(a,wks,(/contour_tc,contour_psl,vector/),pltres,mpres)
  ; plot = wrf_map_overlays(a,wks,(/contour_td,vector/),pltres,mpres)
      gsn_polymarker(wks,plot,116.,40.,pmres)
      frame(wks)
