I've read the article, and I'm not sure if I'm in violation. :)

I've got a series of graphs I generate in R to illustrate backup activity. These are scaled, primarily, in bytes. But different activities have different costs per byte, and I augment the bytes scale with dollars.

http://docs.osg.ufl.edu/tsm/current/ext/UFEXCH-MBX01.AD.UFL.EDU-all.html

So the blue series corresponds to tbe blue dollars scale (and bytes) and the green and red points correspond to the green scale (and bytes).

Am I being naughty?
