Detailed Description

Class for subtracting two histograms

Definition at line 237 of file plotting.py.

Constructor & Destructor Documentation

def plotting.Subtract.__init__ (   self,
  name,
  nameA,
  nameB,
  title = "" 
) 
Constructor

Arguments:
name  -- String for name of the resulting histogram (A-B)
nameA -- String for A histogram
nameB -- String for B histogram

Keyword arguments:
title -- String for a title of the resulting histogram (default "")

Uncertainties are calculated with the assumption that B is a
subset of A, and the histograms contain event counts.
