Re: Plot size (png)

You can use wkWidth and wkHeight to shape a PNG image:

I believe this won't quite work as expected, however, because NCL wants to put all its graphics into a square image.

To add to Dennis' comment, you can also use the -geometry command with convert to create a 1024x768 image.

      convert -geometry 1024-768 -density 128 -trim +repage RRRR.ps RRRR.png
