And A) it's late and B) I tend to install netcdf on everything that
needs it for other things... so it's on my systems. If the docs don't
call for it, OK.

Never have tried to use VNC to accomplish this.

You might set your image type to X11 to show 'em interactively.

You should have something like this in your script:
; We generate plots, but what kind do we prefer?

    type = "x11"
; type = "pdf"
; type = "ps"
; type = "ncgm"

Uncomment the type of file you want to create. It's interpretive so the
last one uncommented will take precedence. I personally never use ncgm.
  You might try 'type = "png" ' and see if that one works for you...
otherwise save it as a pdf. That's a decent output format.
