Class GroupedCategoryDataset

  • All Implemented Interfaces:
    java.io.ObjectInputValidation, java.io.Serializable, java.lang.Cloneable, java.util.EventListener, org.jfree.data.category.CategoryDataset, org.jfree.data.general.Dataset, org.jfree.data.general.DatasetChangeListener, org.jfree.data.KeyedValues2D, org.jfree.data.Values2D
    public class GroupedCategoryDataset
extends org.jfree.data.general.AbstractDataset
implements org.jfree.data.category.CategoryDataset, org.jfree.data.general.DatasetChangeListener, java.io.Serializable
    This class provides methods for automatic grouping of data for the GroupedStackedBarRenderer. This class acts as a dataset itselves, but retrievs the actual data from datasets, that can be added to in order to group data from the datasets with equal row keys.
