Constructor Detail

XIntervalSeries

public XIntervalSeries(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(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.

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.

getDataItem

public ComparableObjectItem getDataItem(int index)
Returns the data item at the specified index.

Parameters: index the item index.

Returns: The data item.

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).

getYValue

public double getYValue(int index)
Returns the y-value for the specified item.

Parameters: index the item index.

Returns: The y-value.
