public class TimeTableXYDataset extends AbstractIntervalXYDataset implements Cloneable, PublicCloneable, IntervalXYDataset, DomainInfo, TableXYDataset
A dataset for regular time periods that implements the TableXYDataset interface. Note that the TableXYDataset interface requires all series to share the same set of x-values. When adding a new item (x, y) to one series, all other series automatically get a new item (x, null) unless a non-null item has already been specified.

    • getDomainIsPointsInTime

      public boolean getDomainIsPointsInTime()
      Returns a flag that controls whether the domain is treated as 'points in time'.

      This flag is used when determining the max and min values for the domain. If true, then only the x-values are considered for the max and min values. If false, then the start and end x-values will also be taken into consideration.

      Returns:
      The flag.
      See Also:

    • setDomainIsPointsInTime

      public void setDomainIsPointsInTime(boolean flag)
      Sets a flag that controls whether the domain is treated as 'points in time', or time periods. A DatasetChangeEvent is sent to all registered listeners.
      Parameters:
      flag - the new value of the flag.

      See Also:

    • setXPosition

      public void setXPosition(TimePeriodAnchor anchor)
