[ncl-talk] colorbar_and_title_not_showing

[Kunal Bali]

Dear NCL users,

I plotted the overlay map, in that the colorbar is coming properly and
title is also missing.

Could you please let  me know the missing point
The script is written below

   BR   = a->BRFLUXV(26,:,:)
   GPH  = a1->H(26,0,:,:)
   u   = a2->uwnd(114,4,:,:)
   v   = a2->vwnd(114,4,:,:)
