[ncl-talk] draw order

[Adam Phillips]

Hi Jian,
Assuming you have tried setting tfPolyDrawOrder = "Draw" and "PreDraw" in
the resource list that you pass to gsn_add_polygon, you can also try
setting tfPolyDrawOrder = "PostDraw" within the resource list that you pass
to gsn_csm_xy.

If neither of those suggestions work one last possibility is to draw the
zero line yourself using gsn_add_polyline, and setting  tfPolyDrawOrder =
"PostDraw" in that resource list..
Hope that helps.. If not, please respond to ncl-talk and include your
script.
Adam
