Thanks again, Bill.
If you mean the black background, then setMatrix() and setAspectCartesian() are the way to go - you just have to get the numerical arguments right ;)
I do mean the black background and will continue to pursue the setMatrix(),setAspectCartesian() approach. It just seemed like there had to be a better way.
I'm having trouble finding documentation on the arguments for setMatrix - can you point me to them?
