Interface IntervalXYDataset

All Superinterfaces:

Dataset, SeriesDataset, XYDataset

All Known Implementing Classes:

AbstractIntervalXYDataset, CategoryTableXYDataset, CombinedDataset, DefaultIntervalXYDataset, DefaultTableXYDataset, DynamicTimeSeriesCollection, HistogramDataset, SimpleHistogramDataset, SubSeriesDataset, TimePeriodValuesCollection, TimeSeriesCollection, TimeTableXYDataset, XIntervalSeriesCollection, XYBarDataset, XYIntervalSeriesCollection, XYSeriesCollection, XYTaskDataset, YIntervalSeriesCollection

public interface IntervalXYDataset
extends XYDataset

An extension of the XYDataset interface that allows an x-interval and a y-interval to be defined. Note that the x and y values defined by the parent interface are NOT required to fall within these intervals. This interface is used to support (among other things) bar plots against numerical axes.

Method Detail

getStartX

java.lang.Number getStartX(int series,
                           int item)

Returns the lower bound of the x-interval for the specified series and item. If this lower bound is specified, it should be less than or equal to the upper bound of the interval (if one is specified).

Parameters:

series - the series index (zero-based).

item - the item index (zero-based).

Returns:

The lower bound of the x-interval (null permitted).

getStartXValue

double getStartXValue(int series,
                      int item)

Returns the lower bound of the x-interval (as a double primitive) for the specified series and item.

Parameters:

series - the series (zero-based index).

item - the item (zero-based index).

Returns:

The lower bound of the x-interval.

getStartX(int, int)

getEndX

java.lang.Number getEndX(int series,
                         int item)

Returns the upper bound of the x-interval for the specified series and item. If this upper bound is specified, it should be greater than or equal to the lower bound of the interval (if one is specified).

Parameters:

series - the series index (zero-based).

item - the item index (zero-based).

Returns:

The upper bound of the x-interval (null permitted).

getEndXValue

double getEndXValue(int series,
                    int item)

Returns the upper bound of the x-interval (as a double primitive) for the specified series and item.

Parameters:

series - the series index (zero-based).

item - the item index (zero-based).

Returns:

The upper bound of the x-interval.

getEndX(int, int)

getStartY

java.lang.Number getStartY(int series,
                           int item)

Returns the lower bound of the y-interval for the specified series and item. If this lower bound is specified, it should be less than or equal to the upper bound of the interval (if one is specified).

Parameters:

series - the series index (zero-based).

item - the item index (zero-based).

Returns:

The lower bound of the y-interval (null permitted).

getStartYValue

double getStartYValue(int series,
                      int item)

Returns the lower bound of the y-interval (as a double primitive) for the specified series and item.

Parameters:

series - the series index (zero-based).

item - the item index (zero-based).

Returns:

The lower bound of the y-interval.

getStartY(int, int)

getEndY

java.lang.Number getEndY(int series,
                         int item)

Returns the upper bound of the y-interval for the specified series and item. If this upper bound is specified, it should be greater than or equal to the lower bound of the interval (if one is specified).

Parameters:

series - the series index (zero-based).

item - the item index (zero-based).

Returns:

The upper bound of the y-interval (null permitted).

getEndYValue

double getEndYValue(int series,
                    int item)

Returns the upper bound of the y-interval (as a double primitive) for the specified series and item.

Parameters:

series - the series index (zero-based).

item - the item index (zero-based).

Returns:

The upper bound of the y-interval.
