Re: Saving pictures

Dear Guilherme,

Since you put the "gsn_open_wks" call inside both do loops, this means that "vetor.00001.png" is getting overwritten each time.

You have two possible solutions:

1. Move the gsn_open_wks call outside both do loops. This will cause each new plot to be draw to a new PNG file
with the names "vetor.00001.png", "vetor.00002.png", etc:

;************************************************
; read in zonal [u] and meridional [v] winds (July)
;************************************************

wks = gsn_open_wks("ps","vetor") ; open a ps file

do t = 0,2

do z = 1,3

2. You can leave the gsn_open_wks call inside the do loops, but you will need to name the file something different each time.
For example, if you want to name the file based on the value of the loop variables "t" and "z", you can do something like this:

do t = 0,2

do z = 1,3
. . .
  ps_filename = "vetor" + t + z
  wks = gsn_open_wks("ps",ps_filename) ; open a ps file

This will give you filenames "vetor00.00001.png", "vector01.00001.png", "vetor02.00001.png", etc.

In the next release of NCL, if you only have one plot in your PNG file, the fileame won't have the ".00001" appended.
The files will simply be "vetor00.png", etc.
