[ncl-talk] PDF plot to big and rotated in 90 degrees.

[Sebastian Otarola-Bustos]

Hi, The other day I tried the improvement, but it didn't work. Here is what
I did:

 do it=0,N_times-1

         u300w = fall[it]->UGRD_P0_L100_GLL0({levs},::-1,:)
         v300w = fall[it]->VGRD_P0_L100_GLL0({levs},::-1,:)
         hgt300= fall[it]->HGT_P0_L100_GLL0({levs(k)},:,:)
         hgt300 at units  = "m"
         tmp300 = fall[it]->TMP_P0_L100_GLL0({levs},::-1,:)
         lat    = fall[it]->lat_0(::-1)
         T300=tmp300({levs(k)},:,:)
         T300=T300-273.15
         U300=u300w({levs(k)},:,:)
         V300=v300w({levs(k)},:,:)
         wks_type            = "png"
         wks_type at wkWidth    = 1700
         wks_type at wkHeight   = 1700

         wks = gsn_open_wks(wks_type,"animate"+sprinti("%03i",it))

         mpid    = gsn_csm_map(wks,mpres)
         hnid  =  gsn_csm_contour(wks,hgt300(:,:),hres)
         T_300  = gsn_csm_contour(wks,T300,Tres)
         V_300   =gsn_csm_vector(wks,U300,V300,Vres)

         ;Overlaps maps in order
         overlay(mpid,hnid)
         overlay(mpid,T_300)
         overlay(mpid,V_300)

         maximize_output(wks,True)
        ;el comando maximize_output hace lo que hacia frame
         delete(wks)
         cmd="convert -trim "+ "animate"+sprinti("%03i",it)+".png"
"animate"+sprinti("%03i",it)+".png"
       system(cmd)
 end do


It's throwing me error when I tried to use the convert command. I was able
to use it without problems for one file, but not yet inside a loop.


Any help would be really helpful,

All the best,
Sebastián.
