[ROOT] connect a line to a ntuple scatter plot

Dear Rooter

My question is if there's a very well correlated scatter plot, 
e.g. x:y from a ntuple, how can I draw a line which pass through all the
points. 

One way to do that is of couse transform this x:y into a 1-D histogram but
it would be much easier if there's a drawing option in ntuple. 

Thank you !
