Re: png output filename issue

TJ,

I should have mentioned this in my last reply. You can use "system" to rename the file after it is created. You will need to call "delete(wks)" before you rename the file, however. The "delete" command closes the file for you.

Try this, after you are completely finished drawing your graphics to "wks":

delete(wks)
system("mv " + wind_gram + ".000001.png " + wind_gram + ".png")

--Mary

In the post referred to below, the ticket refers to "a single image from a script", I create within a loop multiple images with different names based on inputs to the script, will that work under the envisioned scheme? Under the current scheme it creates separate files each with a .000001 in it.
