Re: Title label variable help

[Jaison Kurian <jaison@xxxxxxxxxxxxxxxxxx>]

Hi Selina,
            Here is an example script using the monthly_navy_winds
dataset available with Ferret. Please find the explanations inside
the script. If you have any difficulties, let me know.

Hope this helps 

With Regards 

Jaison

\ cancel mode verify
  
   set data monthly_navy_winds  ! open dataset
   sh da                        ! see the contents of the file

   let ts = "`uwnd,r=tstart`"   ! starting time
   let te = "`uwnd,r=tend`"     ! ending   time
   let txt= "DATE MEANING: start and end date of data collection" ! 51 chars
                                  ! description  
 
   plot/x=70/y=10/set uwnd        ! plot 
      go remove_logo              ! remove ferret logo
      go unlabel 4 ; go unlabel 5 ; go unlabel 6 ! remove time/dset_name 
   ppl plot                       ! deliver the plot

 ! choose proper x and y values to place the labels  

   label `($PPL$XMIN1)*1.3`,12.5,-1,0,0.13 START DATE : `ts`
   label `($PPL$XMIN1)*1.3`,12.0,-1,0,0.13 END   DATE : `te`
   label `($PPL$XMIN1)*1.3`,11.5,-1,0,0.13 `txt`

 ! to write this stuff to a text file
     
   sp rm -f temp.txt ! to remove previous versions
 
   let ts1 = STRCAT("START DATE : ","`ts`")  ! assign a variable name for 
   let te1 = STRCAT("END   DATE : ","`te`")  ! the text in one line (30 chars)

   list/file=temp.txt/nohead/format=(A30) ts1          ! format statemet
   list/file=temp.txt/nohead/format=(A30)/append te1   !  is for a neat
   list/file=temp.txt/nohead/format=(A51)/append txt   !  appearance in the 
   list/x=70/y=10/file=temp.txt/append uwnd            !  text file
