All Known Implementing Classes:
    DefaultTimeline, SegmentedTimeline

A Timeline will present a series of values to be used for an axis. Each Timeline must provide transformation methods between domain values and timeline values. In theory many transformations are possible. This interface has been implemented completely in org.jfree.chart.axis.SegmentedTimeline .

A timeline can be used as parameter to a org.jfree.chart.axis.DateAxis to define the values that this axis supports. As an example, the org.jfree.chart.axis.SegmentedTimeline implements a timeline formed by segments of equal length (ex. days, hours, minutes) where some segments can be included in the timeline and others excluded. Therefore timelines like "working days" or "working hours" can be created where non-working days or non-working hours respectively can be removed from the timeline, and therefore from the axis. This creates a smooth plot with equal separation between all included segments.

Because Timelines were created mainly for Date related axis, values are represented as longs instead of doubles. In this case, the domain value is just the number of milliseconds since January 1, 1970, 00:00:00 GMT as defined by the getTime() method of java.util.Date .

 public boolean containsDomainRange(long fromMillisecond,
    long toMillisecond)
Returns true if a range of values are contained in the
timeline.

 public boolean containsDomainRange(Date fromDate,
    Date toDate)
Returns true if a range of dates are contained in the
timeline.

 public boolean containsDomainValue(long millisecond)
Returns true if a value is contained in the timeline values.

 public boolean containsDomainValue(Date date)
Returns true if a date is contained in the timeline values.

 public long toMillisecond(long timelineValue)
Translates a value relative to this timeline into a domain value. The
domain value obtained by this method is not always the same domain value
that could have been supplied to
translateDomainValueToTimelineValue(domainValue).
This is because the original tranformation may not be complete
reversable.

 public long toTimelineValue(long millisecond)
Translates a millisecond (as defined by java.util.Date) into an index
along this timeline.

 public long toTimelineValue(Date date)
Translates a date into a value on this timeline.
