Constructor Details

VectorSeries

public VectorSeries(Comparable key)

Creates a new empty series.

Parameters:

key - the series key (null not permitted).

VectorSeries

public VectorSeries(Comparable key,
 boolean autoSort,
 boolean allowDuplicateXValues)

Constructs a new series that contains no data. You can specify whether or not duplicate x-values are allowed for the series.

Parameters:

key - the series key (null not permitted).

autoSort - a flag that controls whether or not the items in the series are sorted.

allowDuplicateXValues - a flag that controls whether duplicate x-values are allowed.

Method Details

add

public void add(double x,
 double y,
 double deltaX,
 double deltaY)

Adds a data item to the series.

Parameters:

x - the x-value.

y - the y-value.

deltaX - the vector x.

deltaY - the vector y.

add

public void add(VectorDataItem item,
 boolean notify)

Adds a data item to the series and, if requested, sends a SeriesChangeEvent to all registered listeners.

Parameters:

item - the data item (null not permitted).

notify - notify listeners?

remove

public ComparableObjectItem remove(int index)

Removes the item at the specified index and sends a SeriesChangeEvent to all registered listeners.

Overrides:

remove in class ComparableObjectSeries

Parameters:

index - the index.

Returns:

The item removed.

getXValue

public double getXValue(int index)

Returns the x-value for the specified item.

Parameters:

index - the item index.

Returns:

The x-value.

getYValue

public double getYValue(int index)

Returns the y-value for the specified item.

Parameters:

index - the item index.

Returns:

The y-value.

getVectorXValue

public double getVectorXValue(int index)

Returns the x-component of the vector for an item in the series.

Parameters:

index - the item index.

Returns:

The x-component of the vector.

getVectorYValue

public double getVectorYValue(int index)

Returns the y-component of the vector for an item in the series.

Parameters:

index - the item index.

Returns:

The y-component of the vector.

getDataItem

public ComparableObjectItem getDataItem(int index)

Returns the data item at the specified index.

Overrides:

getDataItem in class ComparableObjectSeries

Parameters:

index - the item index.

Returns:

The data item.
