Hello, I generate some TOY data sets from a PDF within a certain range. Now I want to get the number of data points with different sub-ranges from the generated data sets. The generated toy data distribution is shown here. [Toy_polynomial] . Now I want to get how many events are there in between…

RooDataSet::sumEntries(const char* cutSpec, const char* cutRange = 0) You can either set ranges on the observable, and name them one by one, or you just list cuts such as myDataSet.sumEntries("0 < x && x < 5"). Replace x with the name of your observable.

Get number of entries within certain range from TOY generated data sets
