Hi Gary,
I don't think you can get rid of the warning message, but if you set
the trYMinF and trYMaxF resources to the limits that you want the Y
axis to have, then you should see your constant line. So, for
example, if your constant line is at Y=100., then you could set
trYMinF to something < 100, like 95, and trYMaxF to something > 100,
like 105.
Using a GSUN interface, it would look something like:
res@trYMinF = 95.
res@trYMaxF = 105.
xy = gsn_xy(wks,...,res)
Using straight NCL:
xy = create "xyplot" xyPlotClass wks
...
"trYMinF" : 95.
"trYMaxF" : 105.
...
end create
