[ncl-talk] trajectories with annotate_4.ncl script

[Henri Rossi Pinheiro]

hi Rick

I'm sorry forgot to say that the original script is setup as the following
way as you comment:

   xp = new((/5,4/),float)            ; allocate memory
   yp = new((/5,4/),float)

But how would you do if having two tracks with different lengths for example

;best track
   yp(0,:) = (/ 29.1,   30.3,   31.7,   33.5/)
   xp(0,:) = (/-94.6,  -95.2,  -95.3,  -94.9/)
;da
   yp(1,:) = (/ 29.12,  30.02,  31.29,  33.05,  34.20/)
   xp(1,:) = (/-94.87, -95.08, -95.13, -94.65, -94.50/)

Regards

Henri
