[ncl-talk] Transects

[Karin Meier-Fleischer]

Hi Soma,

the warning is telling you exactly what is wrong. Your latitude values 
associated with your variable t is decreasing not increasing.

       level: [   1.. 60]
*      latitude: [40.. 0]*
     longitude: [65..100]

Reorder lat dimension of the variable t = t(:,::-1,:)
