Re: legend for multi-curves on panel plot

Hi Hongyan,
If you are paneling, it is recommended that you use gsn_add_text and
gsn_add_polyline and not gsn_polyline/gsn_text. See the documentation here:
http://www.ncl.ucar.edu/Document/Graphics/Interfaces/gsn_add_text.shtml
http://www.ncl.ucar.edu/Document/Graphics/Interfaces/gsn_add_polyline.shtml

Try switching to those two functions and let ncl-talk know if that does
not fix your issue.
