public class Histogram
extends Object

A histogram is a graphical display of tabulated frequencies, shown as bars. It shows what proportion of cases fall into each of several categories: it is a form of data binning. The categories are usually specified as non-overlapping intervals of some variable. The categories (bars) must be adjacent. The intervals (or bands, or bins) are generally of the same size, and are most easily interpreted if they are.

public Histogram()

Method Details

of

public static BarPlot of(int[] data)

Creates a histogram plot. The number of bins will be determined by square-root rule and the y-axis will be in the probability scale.

Parameters:

data - a sample set.

of

public static BarPlot of(int[] data,
 int k,
 boolean prob)

Creates a histogram plot.

Parameters:

data - a sample set.

k - the number of bins.

prob - if true, the y-axis will be in the probability scale. Otherwise, y-axis will be in the frequency scale.

of

public static BarPlot of(int[] data,
 int k,
 boolean prob,
 Color color)

Creates a histogram plot.

Parameters:

data - a sample set.

k - the number of bins.

prob - if true, the y-axis will be in the probability scale. Otherwise, y-axis will be in the frequency scale.

of

public static BarPlot of(int[] data,
 double[] breaks,
 boolean prob)

Creates a histogram plot.

Parameters:

data - a sample set.

breaks - an array of size k+1 giving the breakpoints between histogram cells. Must be in ascending order.

prob - if true, the y-axis will be in the probability scale. Otherwise, y-axis will be in the frequency scale.

of

public static BarPlot of(int[] data,
 double[] breaks,
 boolean prob,
 Color color)
