Examples of org.jfree.chart.axis.SegmentedTimeline$Segment

org.jfree.chart.axis.SegmentedTimeline
Internal class to represent a valid segment for this timeline. A segment is valid on a timeline if it is part of its included, excluded or exception segments.
Each segment will know its segment number, segmentStart, segmentEnd and index inside the segment.
