Re: Overlap draw of polyline and polygon.

Hi,

If you plot the polygon first and then the polyline, that should fix the
problem:

First plot polygon:

 xpm = new( (/2/), float )
 ypm = new( (/2/), float )
 xpm = (/1.,96./)
 daym = data_mean(mm)
 ypm = (/daym,daym/)

 gsres1 = True ; poly res
 gsres1_at_gsFillColor = "grey" ; color chosen
dummy1(mm) = gsn_add_polygon (wks,plot(mm),xp(mm,:),yp(mm,:),gsres1)

Then plot the polyline:

 gsres = True

 gsres_at_gsLineColor = "brown"
 gsres_at_gsLineThicknessF = 3.
 dummy0(mm) = gsn_add_polyline(wks,plot(mm),xpm,ypm,gsres)

I hope it works the way you want,
Erwan
