Constructor Details

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 Details

add

public void add(double x,
                double xLow,
                double xHigh,
                double y)
Adds a data item to the series.
Parameters:
x - the x-value.
xLow - the lower bound of the y-interval.
xHigh - the upper bound of the y-interval.
y - the y-value.

getDataItem

public ComparableObjectItem getDataItem(int index)
Returns the data item at the specified index.
Overrides:
getDataItem in interface ComparableObjectSeries
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.
