Constructor Detail

VectorSeries

public VectorSeries(java.lang.Comparable key)

Creates a new empty series.

Parameters:

key - the series key (null not permitted).

VectorSeries

public VectorSeries(java.lang.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 Detail

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?

Since:

1.0.18
