Histogram2

public Histogram2(String name,
                  int nBinsX,
                  double minX,
                  double maxX,

                  double minY,
                  double maxY)

Creates 2D histogram with name and ranges [minX, maxX] and [minY, maxY]

Parameters:

name - of the data sets

nBinsX - number of horizontal bins

minX - minimum of horizontal range

maxX - maximum of horizontal range

nBinsY - number of vertical bins

minY - minimum of vertical range

maxY - maximum of vertical range

Method Detail

fill

public int fill(double x,
                double y)

Description copied from interface: Histogram2D

Increment bin with abscissa X, Y, and Z by 1. if x is less than the low-edge of the first bin, the Underflow bin is incremented if x is equal to or greater than the upper edge of last bin, the Overflow bin is incremented

Specified by:

fill in interface Histogram2D

Parameters:

x - new value to be added

y - new value to be added

Returns:

corresponding bin number which has its content incremented by 1

fill

public int fill(double x,
                double y,
                double w)

Description copied from interface: Histogram2D

Increment bin with abscissa X by with a weight w. if x is less than the low-edge of the first bin, the Underflow bin is incremented if x is equal to or greater than the upper edge of last bin, the Overflow bin is incremented

Specified by:

fill in interface Histogram2D

Parameters:

x - new value to be added

y - new value to be added

w - weight

Returns:

corresponding bin number which has its content incremented by 1

findFirstBinAbove

public int findFirstBinAbove(double x,
                             double y)

Specified by:

findFirstBinAbove in interface Histogram2D

Parameters:

x - spatial real-valued coordinate in X

y - spatial real-valued coordinate in Y

Returns:

bin index that is above the spatial x and y coordinates

get

public double get(int dimIndex,
                  int binIndex)

Description copied from interface: DataSet

Gets the x value of the data point with the index i
