In the top left, under "Player" change it from your name and choose the villain you want to see. 
 
Please remember that the graph will be from their point of view, not yours, so it's *not* a good thing if it is going up! ;-) 
 
Also, as it is from their point of view, that includes rake. Players often forget that if their hyper has 2.1% rake per player, and the villain has a -1.5% ev roi, they shouldn't be excited, they have a -2.7% themselves.
