Examples of org.jfree.data.xy.YWithXInterval

org.jfree.data.xy.YWithXInterval
A y-value plus the bounds for the related x-interval. This curious combination exists as an implementation detail, to fit into the structure of the ComparableObjectSeries class. It would have been possible to simply reuse the {@link YInterval} class by assuming that the y-intervalin fact represents the x-interval, however I decided it was better to duplicate some code in order to document the real intent. @since 1.0.3
