Package etomica.data.histogram

Class HistogramNotSoSimple

java.lang.Object

etomica.data.histogram.HistogramNotSoSimple

All Implemented Interfaces:

Histogram, java.io.Serializable

public class HistogramNotSoSimple
extends java.lang.Object
implements Histogram, java.io.Serializable

Histogram implementation with a static x range and number of bins. If an x value is given that falls outside the histogram's x range, the value is dropped. The x range and number of bins can be changed explicitly, but doing so will reset the histogram (losing all previously collected data). Values are added in pairs (x and y). The average value of y is calculated for each x bin.

Constructor Detail

HistogramNotSoSimple

public HistogramNotSoSimple(DoubleRange xRange)

Makes a new histogram instance, with the range of x values given by xRange.

HistogramNotSoSimple

public HistogramNotSoSimple(int n,
                            DoubleRange xRange)

Makes a new histogram instance, with the range of x values given by xRange and n bins.

Method Detail

reset

public void reset()

Description copied from interface: Histogram

resets all histogram values and counts to zero

Specified by:

reset in interface Histogram

addValue

public void addValue(double x,
                     double y)

addValue

public void addValue(double x)

Description copied from interface: Histogram

Adds the given value to the Histogram

Specified by:

addValue in interface Histogram

setXRange

public void setXRange(DoubleRange xRange)

Description copied from interface: Histogram

Sets the range of x values used in the histogram (min and max). The existing histogram may be dropped or redistributed to the new bins.

Specified by:

setXRange in interface Histogram

getXRange

public DoubleRange getXRange()

Description copied from interface: Histogram

Returns the range of x values (min and max) used in the histogram.

Specified by:

getXRange in interface Histogram

getNBins

public int getNBins()

Description copied from interface: Histogram

Returns the number of bins in the histogram.

Specified by:

getNBins in interface Histogram

setNBins

public void setNBins(int n)

Description copied from interface: Histogram

Sets the number of bins used by the Histogram. The existing histogram may be dropped or redistributed to the new bins.

Specified by:

setNBins in interface Histogram

getHistogram

public double[] getHistogram()

Description copied from interface: Histogram

Returns the histogram as an array of doubles

Specified by:

getHistogram in interface Histogram

setDoAveraging

public void setDoAveraging(boolean doAveraging)

turns "averaging" on or off. With averaging, the value of the histogram is the average value of y for that x. Without averaging, the y value is used to weight the histogram

getDoAveraging

public boolean getDoAveraging()

getCount

public long getCount()

Description copied from interface: Histogram

Returns the number of times the Histogram's addValue method was called.

Specified by:

getCount in interface Histogram

xValues

public double[] xValues()

Description copied from interface: Histogram

Returns the x values from the histogram as an array of doubles

Specified by:

xValues in interface Histogram
