public interface Histogram
extends DataSet, DataSetMetaData

Specialized DataSet interface for storing and processing Histogram data. A histogram with bins 1...N is defined by n+1 values defining the steps between the bins. The bins can be equidistant or not. The bins 0 and N+1 have a special meaning and contain the data for data which is out of range. They are not drawn by default.

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

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
