Constructor & Destructor Documentation

PseudoHistogram::PseudoHistogram	(	int	NOfBins,
		double	min,
		double	max
	)

Constructor with number of bins and lower and upper boundaries.

Parameters

NOfBins	: number of bins in the histogram. Over- and underflow bin are created additionally.
min	: smallest value in the histogram
max	: largest value in the histogram

Member Function Documentation

void PseudoHistogram::fill	(	double	x,
		double	w
	)

Fill a value x with the weight w to the pseudo-histogram.

Parameters

x	: value to fill in the histogram
w	: weight of the value x

int PseudoHistogram::findBin

(

double

x

)

Find the bin containing x.

Parameters

x	: value on the x axis

Returns

the bin containing x

double PseudoHistogram::getBinContent

(

int

bin

)

Returns content of bin.

Parameters

bin	: number of the bin

int PseudoHistogram::getNumberOfEntries

(

int

bin

)

Returns number of entries in bin.

Parameters

bin	: number of the bin

References isInRange().

double PseudoHistogram::integral	(	int	startbin,
		int	endbin
	)

Returns the weighted sum of the pseudo-histogram within startbin and endbin.

Parameters

startbin	: number of the start bin for the integral
endbin	: number of the end bin for the integral

References getBinContent(), and isInRange().

bool PseudoHistogram::isInRange

(

int

bin

)

Checks if bin is in range of the pseudo-histogram (over- and underflow bins are taken into account)

Parameters

bin	: number of the bin
