Examples of org.jfree.data.time.TimeSeriesCollection

org.jfree.data.time.TimeSeriesCollection
A collection of time series objects. This class implements the {@link XYDataset} interface, as well as the extended{@link IntervalXYDataset} interface. This makes it a convenient dataset foruse with the {@link org.jfree.chart.plot.XYPlot} class.
