Constructor Detail

XIntervalSeries

public XIntervalSeries(java.lang.Comparable key)

Creates a new empty series. By default, items added to the series will be sorted into ascending order by x-value, and duplicate x-values will be allowed (these defaults can be modified with another constructor.

Parameters:

key - the series key (null not permitted).

XIntervalSeries

public XIntervalSeries(java.lang.Comparable key,
                       boolean autoSort,
                       boolean allowDuplicateXValues)

Constructs a new xy-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 xLow,
                double xHigh,
                double y)

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

Parameters:

x - the x-value.

y - the y-value.

xLow - the lower bound of the y-interval.

xHigh - the upper bound of the y-interval.

add

public void add(XIntervalDataItem 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

getX

public java.lang.Number getX(int index)

getXHighValue

public double getXHighValue(int index)

Returns the upper bound of the x-interval for the specified item.

Parameters:

index - the item index.

Returns:

The upper bound of the x-interval.

Since:

1.0.10

getYValue

public double getYValue(int index)

Returns the y-value for the specified item.

Parameters:

index - the item index.

Returns:

The y-value.

Returns the data item at the specified index.

Overrides:

getDataItem in class ComparableObjectSeries

Parameters:

index - the item index.

Returns:

The data item.
