i am starting to use this tool more and am needing a option for a white backround choice. 
i like to print the graph for customers and black takes alot of ink, plus i don't like the contrast. 
i already have a ease pc based scan tool program and it uses a white backround which works fine.
your product is easier to use for a quick test drive.
please add a choice for white backround, please.

What a great idea. This would keep my printer from mopping all of that black ink!!

Good post,
