public class TimeSeriesCollection extends AbstractIntervalXYDataset implements XYDataset, IntervalXYDataset, DomainInfo, XYDomainInfo, XYRangeInfo, VetoableChangeListener, Serializable
A collection of time series objects. This class implements the XYDataset interface, as well as the extended IntervalXYDataset interface. This makes it a convenient dataset for use with the XYPlot class.
