[ncl-talk] any easy way to use gsn_text to add curved text?

[Mary Haley]

I think the problem is that you haven't provided enough points in the line
to hold the full text.

I tried using some dummy lat/lon values for the polyline (along with a
dummy wrfout file), and was able to get the text. Here are the dummy values
I used, and the code for drawing the text:

  lat = (/ 30, 31, 32, 35, 37, 40, 41, 42, 43, 44, 45/)
  lon = (/-95,-94,-90,-90,-90,-88,-87,-87,-85,-83,-82/)
  gsres = True
  gsres at gsLineLabelString = "B|a|l|c|o|n|es F|a|u|lt"
  gsn_polyline(wks,plot,lon(1:),lat(1:),gsres)

See the attached image.
