Description

Interface Summary
CombinationDataset | Interface that describes the new methods that any combined dataset needs to implement.
Dataset | The base interface for data sets.
DatasetChangeListener | The interface that must be supported by classes that wish to receive notification of changes to a dataset.
KeyedValueDataset | A dataset containing a single value.
KeyedValues2DDataset | A dataset containing (key, value) data items.
KeyedValuesDataset | A dataset containing (key, value) data items.
PieDataset | A general purpose dataset where values are associated with keys.
SeriesChangeListener | Methods for receiving notification of changes to a data series.
SeriesDataset | The interface for a dataset consisting of one or many series of data.
ValueDataset | An interface for a dataset that returns a single value.

Class Summary
AbstractDataset | An abstract implementation of the `Dataset` interface, containing a mechanism for registering change listeners.
AbstractSeriesDataset | An abstract implementation of the `SeriesDataset` interface, containing a mechanism for registering change listeners.
CombinedDataset | This class can combine instances of `XYDataset`, `OHLCDataset` and `IntervalXYDataset` together exposing the union of all the series under one dataset.
DatasetChangeEvent | A change event that encapsulates information about a change to a dataset.
DatasetGroup | A class that is used to group datasets (currently not used for any specific purpose).
DatasetUtilities | A collection of useful static methods relating to datasets.
DefaultKeyedValueDataset | A default implementation of the `KeyedValueDataset` interface.
DefaultKeyedValues2DDataset | A default implementation of the `KeyedValues2DDataset` interface.
DefaultKeyedValuesDataset | A default implementation of the `KeyedValuesDataset` interface.
DefaultPieDataset | A default implementation of the `PieDataset` interface.
DefaultValueDataset | A dataset that stores a single value (that is possibly `null`).
Series | Base class representing a data series.
SeriesChangeEvent | An event with details of a change to a series.
SubSeriesDataset | This class will create a dataset with one or more series from another `SeriesDataset`.
WaferMapDataset | A dataset that can be used with the `WaferMapPlot` class.

Exception Summary
SeriesException | A general purpose exception class for data series.
