Nifty! If you want to play with these a bit take a peek at this snapshot, and while you’re at it I want you to try something. As you’re mousing over one graph or the other, try holding down the shift key and see what happens. It’s subtle (and you’ll only see what I’m talking about if the page has more than one
inGraph on it) but I think you’ll be pleasantly surprised. I know I was.
