weightgrapher and TOM

tracymayo1

I see on the site that it should be tracking my TOM and I remember reading on here somewhere it can superimpose TOM over your weight info so you can see when you gain/lose around this time.

However, I cannot for the life of me figure out how to work it?
Wouldn't I have to enter my last TOM for it to track and such? And I only see the 2 lines on my graph. the one with the dots showing trend and the blue solid line above that one...

I want to use all the functions but there aren't really instructions on how - or I havent found them...
