Constructor Details

XYIntervalSeries

public XYIntervalSeries(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).

XYIntervalSeries

public XYIntervalSeries(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 Details

add

public void add(double x,
 double xLow,
 double xHigh,
 double y,
 double yLow,
 double yHigh)

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

Parameters:

x - the x-value.

xLow - the lower bound of the x-interval.

xHigh - the upper bound of the x-interval.

y - the y-value.

yLow - the lower bound of the y-interval.

yHigh - the upper bound of the y-interval.

add

public void add(XYIntervalDataItem 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?

getX

public Number getX(int index)

Returns the x-value for the specified item.

Parameters:

index - the item index.

Returns:

The x-value (never null).

getXLowValue

public double getXLowValue(int index)

Returns the lower bound of the x-interval for the specified item in the series.

Parameters:

index - the item index.

Returns:

The lower bound of the x-interval.

getXHighValue

public double getXHighValue(int index)

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

Parameters:

index - the item index.

Returns:

The upper bound of the x-interval.

getYValue

public double getYValue(int index)

Returns the y-value for the specified item.

Parameters:

index - the item index.

Returns:

The y-value.

getYLowValue

public double getYLowValue(int index)

Returns the lower bound of the Y-interval for the specified item in the series.

Parameters:

index - the item index.

Returns:

The lower bound of the Y-interval.

getYHighValue

public double getYHighValue(int index)

Returns the upper bound of the y-interval for the specified item in the series.

Parameters:

index - the item index.

Returns:

The upper bound of the y-interval.

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.
