Method Detail

addBinContent

void addBinContent(int bin)

Increment bin content by 1. More...

Parameters:

bin - global bin ID

addBinContent

void addBinContent(int bin,
                   double w)

Increment bin content by a weight w. More...

Parameters:

bin - global bin ID

w - weight

findBin

int findBin(double x,
            double y)

Parameters:

x - spatial real-valued coordinate in X

y - spatial real-valued coordinate in Y

Returns:

bin index corresponding to spatial x and y coordinates

findBin

int findBin(double x,
            double y,
            double z)

Parameters:

x - spatial real-valued coordinate in X

y - spatial real-valued coordinate in Y

z - spatial real-valued coordinate in Z

Returns:

bin index corresponding to spatial x, y and z coordinates

findBin

int findBin(int dimIndex,
            double x)

Parameters:

dimIndex - the dimension index

x - spatial real-valued coordinate for dimension dimIndex

Returns:

bin index corresponding to spatial x and y coordinates

getBinCenter

double getBinCenter(int dimIndex,
                    int binIndex)

Parameters:

dimIndex - the dimension index

binIndex - index

Returns:

bin centre for axis with dimIndex

getBinContent

double getBinContent(int bin)

Return content of bin number bin. Convention for numbering bins For all histogram types: nbins, xlow, xup bin = 0; underflow bin bin = 1; first bin with low-edge xlow INCLUDED bin = nbins; last bin with upper-edge xup EXCLUDED bin = nbins+1; overflow bin

Parameters:

bin - the index

Returns:

numeric bin content

isEquiDistant

boolean isEquiDistant()

Returns:

true if bin sizes are equal

reset

void reset()

reset histogram content
