Trajectory With color Gradient

Dear NCL users,

I am trying to plot a trajectory over the south pole, where the data is in
the format
lon, lat, parameter (untraj.dat)
I have to plot this trajectory with the parameter in different colors as its
value changes (like a contour along the trajectory).
I am able to draw the trajectory, but not able to do it with different
colors. How do I make it with different colors (i.e I have to change the Red
colored line into a line with different colors as the parameter varies and a
colorbar). I have attached the files.
Can you help me?

Thanks & Regards

Satheesan
