Interface IntervalXYZDataset

All Superinterfaces:
  Dataset, SeriesDataset, XYDataset, XYZDataset

    public interface IntervalXYZDataset

extends XYZDataset

An extension of the `XYZDataset` interface that allows a range of data to be defined for any of the X values, the Y values, and the Z values.

Method Summary
`java.lang.Number` | `getEndXValue(int series, int item)` Returns the ending X value for the specified series and item.
`java.lang.Number` | `getEndYValue(int series, int item)` Returns the ending Y value for the specified series and item.
`java.lang.Number` | `getEndZValue(int series, int item)` Returns the ending Z value for the specified series and item.
`java.lang.Number` | `getStartXValue(int series, int item)` Returns the starting X value for the specified series and item.
`java.lang.Number` | `getStartYValue(int series, int item)` Returns the starting Y value for the specified series and item.
`java.lang.Number` | `getStartZValue(int series, int item)` Returns the starting Z value for the specified series and item.
