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.
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.

XYIntervalSeries: A list of (x, x-low, x-high, y, y-low, y-high) data items.
XYIntervalSeriesCollection: A collection of `XYIntervalSeries` objects.
XYSeries: Represents a sequence of zero or more data items in the form (x, y).
XYSeriesCollection: Represents a collection of `XYSeries` objects that can be used as a dataset.
