Liping,
Try this:
res@gsnZonalMean = True ; Draw a Zonal mean
plot(0) = gsn_csm_contour_map_ce(wks,ABS, res)
setvalues plot@xy
"trXMinF" : -200
"trXMaxF" : 400
"gsnXRefLine": 0.0 ; draw a reference line
end setvalues
resp = True ; polyline mods desired
resp@gsLineThicknessF = 2.0 ; thickness of lines
dum = gsn_add_polyline(wks,plot@xy,(/0,0/),(/-200,400/),resp)
I haven't tested it, but I believe it should work.
