# Package org.jfree.data.xy

A package containing the

`XYDataset`

interface and related classes.-
Interface Summary Interface Description IntervalXYDataset An extension of the`XYDataset`

interface that allows an x-interval and a y-interval to be defined.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. -
