Constructor & Destructor Documentation

__init__()

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.
