Examples of org.jfree.data.time.TimePeriodValuesCollection

org.jfree.data.time.TimePeriodValuesCollection
A collection of {@link TimePeriodValues} objects.
This class implements the {@link org.jfree.data.xy.XYDataset} interface, aswell as the extended {@link IntervalXYDataset} interface. This makes it aconvenient dataset for use with the {@link org.jfree.chart.plot.XYPlot}class.
