public interface Timeline
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
SegmentedTimeline
.
A timeline can be used as parameter to a
DateAxis
to define the values that this axis
supports. As an example, the 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 Date
.
