Number of Entries in a histogram above a value

ROOT Version: 6.14.00

Hey all!

How might I be able to retrieve the number of histogram entries above an x-axis value from a histogram present in a tree? I’m attempting to plot values of one histogram versus values of another histogram when cuts are made on it by the first.

Thanks in advance,

See the “selection” parameter of the TTree::Draw method.
