Examples of org.jfree.data.extension.impl.XYDatasetSelectionExtension$XYDatasetSelectionIterator

org.jfree.data.extension.impl.XYDatasetSelectionExtension
Allows to iterate over all data items or the selected / unselected data items. Provides on each iteration step a DatasetCursor that defines the position of the data item. @author zinsmaie
