It depends on your definition of easy. People who use LabVIEW every day would consider it easy. Others would not. The thing is that graphs have LOTS of properties. One guy took the time to write some great VIs to save and load those properties. Don't try to pronounce his name, it's Konstantin Shifershteyn.
Find his utility called Property Saver here -> http://www.kshif.com/lv/index.html
It doesn't do exactly what you want, but you should be able to locate the code that reads ALL the graph properties. Then, locate the code that writes them back. Stitch those together and you've got it.
Your friendly neighborhood Alliance Member would be glad to do that for you if you can cut a small PO. We do this stuff every day.
