Examples of XYTaskDataset

org.jfree.data.gantt.XYTaskDataset
A dataset implementation that wraps a {@link TaskSeriesCollection} andpresents it as an {@link IntervalXYDataset}, allowing a set of tasks to be displayed using an {@link XYBarRenderer} (and usually a{@link SymbolAxis}). This is a very specialised dataset implementation ---before using it, you should take some time to understand the use-cases that it is designed for. @since 1.0.11
