[ncl-talk] Main title not appearing in the plot

[Rick Brownrigg]

Hi,

I don't know for certain, but two things stand out.  One is that the script
sets many resources on the variable "res", but never uses it; insteads
variables "pltres" and "mpres" get passed to the call to
wrf_map_overlays(). Additionally, while the variable "plot" is assigned the
return value of wrf_map_overlays(), it is then overwritten two lines later
in the call to add_coastline_sgmyid(). I am unfamiliar with that function,
and uncertain as to what the result should be.

I hope that helps...
Rick
