Field Detail

data

protected double[] data

The raw data to be organized. This will usually be set via the setData() method.

min

protected double min

max

protected double max

intervals

protected int intervals

Constructor Detail

Histogram

public Histogram(double min,
                 double max,
                 int intervals)

Creates a new histogram.

Parameters:

min - The minimum data value to be included

max - The maximum data value to be included

intervals - The number of intervals into which the range should be divided

Method Detail

solve

public void solve(double x0,
                  double step,
                  double[] solns)

Fills the supplied area with "step function data". If plotted, the data will form either a series of horizontal bars, or (if interpolation is enabled on the Plotter) the outline of a bar graph.

Specified by:

solve in interface Solvable

Tags copied from interface: Solvable

Parameters:

x0 - The initial x-value

step - The increment to be applied to x0

vals - The array which will hold the solution data

getFreqs

public int[] getFreqs()

Produces a frequency table for the collected data, with intervals as specified in the constructor.

getData

public double[] getData()

Returns the raw data

setData

public void setData(double[] d)

Sets the raw data
