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

org.jfree.chart.axis.SegmentedTimeline
Private internal class to represent a range of segments. This class is mainly used to store in one object a range of exception segments. This optimizes certain timelines that use a small segment size (like an intraday timeline) allowing them to express a day exception as one SegmentRange instead of multi Segments.
