Getting entries from branch and plotting entry# as a bin in a histogram

What I am trying to do is take the entries from an existing branch and make a new 1D histogram where the entries from my branch are plotted as bins. So for example, my x axis would be the entry number and the y axis would be the value of that entry. From there I want to integrate the histogram to get the total summation of all the entries.

If someone could explain how to do this it would be much appreciated!!


please take a look here for an overview of the different methods available to read values of a branch and fill a histogram.

Once you have the histogram filled, if I understand correctly you would just need to call ComputeIntegral on it (see the docs).
