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.

                double deltaY)
Adds a data item to the series.
Parameters:
x - the x-value.
y - the y-value.
