## Package org.jfree.data.xy

A package containing the `XYDataset` interface and related classes.

Description

Interface Summary
IntervalXYDataset | An extension of the `XYDataset` interface that allows a range of data to be defined for the X values, the Y values, or both the X and Y values.
IntervalXYZDataset | 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.
OHLCDataset | An interface that defines data in the form of (x, high, low, open, close) tuples.
TableXYDataset | A dataset containing one or more data series containing (x, y) data items, where all series in the dataset share the same set of x-values.
VectorXYDataset | An extension of the `XYDataset` interface that allows a vector to be defined at a specific (x, y) location.
WindDataset | Interface for a dataset that supplies wind intensity and direction values observed at various points in time.
XisSymbolic | Represent a data set where X is a symbolic values.
XYDataset | An interface through which data in the form of (x, y) items can be accessed.
XYDomainInfo | An interface that can (optionally) be implemented by a dataset to assist in determining the minimum and maximum x-values in the dataset.
XYRangeInfo | An interface that can (optionally) be implemented by a dataset to assist in determining the minimum and maximum y-values.
XYZDataset | The interface through which JFreeChart obtains data in the form of (x, y, z) items - used for XY and XYZ plots.
YisSymbolic | Represent a data set where Y is a symbolic values.

Class Summary
AbstractIntervalXYDataset | An base class that you can use to create new implementations of the `IntervalXYDataset` interface.
AbstractXYDataset | An base class that you can use to create new implementations of the `XYDataset` interface.
AbstractXYZDataset | An base class that you can use to create new implementations of the `XYZDataset` interface.
CategoryTableXYDataset | An implementation variant of the `TableXYDataset` where every series shares the same x-values (required for generating stacked area charts).
DefaultHighLowDataset | A simple implementation of the `OHLCDataset` interface.
DefaultIntervalXYDataset | A dataset that defines a range (interval) for both the x-values and the y-values.
DefaultOHLCDataset | A simple implementation of the `OHLCDataset` interface.
DefaultTableXYDataset | An `XYDataset` where every series shares the same x-values (required for generating stacked area charts).
DefaultWindDataset | A default implementation of the `WindDataset` interface.
DefaultXYDataset | A default implementation of the `XYDataset` interface that stores data values in arrays of double primitives.
DefaultXYZDataset | A default implementation of the `XYZDataset` interface that stores data values in arrays of double primitives.
