Position of Double_t xmax, Double_t ymax) bottom of box is calculated automatically from number lines in box Cut(const char* expression) – Apply given cut expression to data when calculating statistics CutRange(const char* rangeName) – Only consider events within given range when calculating statistics. Multiple CutRange() argument may be specified to combine ranges
The Format(const char* what,...) has the following structure
const char* what – Controls what is shown. "N" adds name, "E" adds error, "A" shows asymmetric error, "U" shows unit, "H" hides the value FixedPrecision(int n) – Controls precision, set fixed number of digits AutoPrecision(int n) – Controls precision. Number of shown digits is calculated from error
