Re: Trajectory With color Gradient

Hi Jonathan,

Thank you for your suggestion. I made some changes to the traj_2.ncl and
still I am unable to get the colours. It complains that " Not enough colors
in colormap for number of contour levels" and plotting a black line. Also it
is plotting under the map. What could be the problem.

Thanks & Regards,

Satheesan
