Examples of org.jfree.data.time.TimePeriodValues

org.jfree.data.time.TimePeriodValues
A structure containing zero, one or many {@link TimePeriodValue} instances. The time periods can overlap, and are maintained in the order that they are added to the collection.
This is similar to the {@link TimeSeries} class, except that the time periods can have irregular lengths.

    JRPrintHyperlink printHyperlink = null;
    if (hasHyperlinks() && entity instanceof XYItemEntity)
    {
      XYItemEntity itemEntity = (XYItemEntity) entity;
      TimePeriodValuesCollection dataset = (TimePeriodValuesCollection) itemEntity.getDataset();
      TimePeriodValues series = dataset.getSeries(itemEntity.getSeriesIndex());
      Map serieHyperlinks = (Map) itemHyperlinks.get(series.getKey());
      if (serieHyperlinks != null)
      {
        TimePeriod timePeriod = series.getTimePeriod(itemEntity.getItem());
        printHyperlink = (JRPrintHyperlink) serieHyperlinks.get(timePeriod);
