All Implemented Interfaces:

ITrace2D, java.beans.PropertyChangeListener, java.io.Serializable, java.lang.Comparable<ITrace2D>, java.util.EventListener

public class Trace2DArithmeticMean
extends ATrace2D

A trace that accumulates the latest n points added to points with the arithmetic mean value.

This trace will not reduce the amount of n points added to one carrying the arithmetic mean but always add a point that has the average of the recent added n points.

Please note that this trace scan be used in two modes:

1. Stand alone:
   Add the ITrace2D implementation to a chart and add data points to it as normal.
2. Computing trace:
   Add the ITrace2D implementation as a computing trace to an existing trace via ITrace2D.addComputingTrace(info.monitorenter.gui.chart.ITrace2D) and only add data points to the original trace. Add the computing trace to the same chart and updates of the original trace will be reflected on the computing trace as well.

Since:

7.0.0

Constructor Detail

Trace2DArithmeticMean

public Trace2DArithmeticMean(int arithmenticMeanSpan)

The amount of n recent points to buffer. private int m_pointBufferSize; /** Constructor with the given amount of points to merge into one point with their arithmetic mean.

Parameters:

arithmenticMeanSpan - the amount of points to merge into one point with their arithmetic mean.

Method Detail

equals

public boolean equals(java.lang.Object obj)

Overrides:

equals in class java.lang.Object

See Also:

Object.equals(java.lang.Object)

getMaxSize

public int getMaxSize()

Description copied from interface: ITrace2D

Returns the maximum amount of TracePoint2D instances that may be added. For implementations that limit the maximum amount this is a reasonable amount. Non-limiting implementations should return Integer.MAX_VALUE. This allows to detect the unlimitedness. Of course no implementation could store that amount of points.

Returns:

The maximum amount of TracePoint2D instances that may be added.

See Also:

ITrace2D.getMaxSize()

getSize

public int getSize()

Description copied from interface: ITrace2D

Returns the amount of TracePoint2D instances currently contained.

Returns:

The amount of TracePoint2D instances currently contained.

See Also:

ITrace2D.getSize()

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

See Also:

Object.hashCode()

isEmpty

public boolean isEmpty()

Description copied from interface: ITrace2D

Returns false if internal TracePoint2D instances are contained or true if not.

Returns:

false if internal TracePoint2D instances are contained or true if not.

See Also:

ITrace2D.isEmpty()

iterator

public java.util.Iterator<ITracePoint2D> iterator()

Description copied from interface: ITrace2D

Returns an Iterator over the internal TracePoint2D instances.

Implementations should be synchronized. This method is meant to allow modifications of the intenal TracePoint2D instances, so the original points should be returned.

There is no guarantee that changes made to the contained tracepoints will be reflected in the display immediately. The order the iterator returns the TracePoint2D instances decides how the Chart2D will paint the trace.

Returns:

an Iterator over the internal TracePoint2D instances.
