Class GroupedStackedBarRenderer

  • All Implemented Interfaces:
    java.io.Serializable, java.lang.Cloneable, LegendItemSource, CategoryItemRenderer, org.jfree.util.PublicCloneable

    public class GroupedStackedBarRenderer
    extends StackedBarRenderer
    implements java.lang.Cloneable, org.jfree.util.PublicCloneable, java.io.Serializable
    A renderer that draws stacked bars within groups. This will probably be merged with the StackedBarRenderer class at some point. The example shown here is generated by the StackedBarChartDemo4.java program included in the JFreeChart Demo Collection:

    • Method Detail

      • calculateBarWidth

        protected void calculateBarWidth​(CategoryPlot plot,
                                         java.awt.geom.Rectangle2D dataArea,
                                         int rendererIndex,
                                         CategoryItemRendererState state)
        Calculates the bar width and stores it in the renderer state. We override the method in the base class to take account of the series-to-group mapping.
        Overrides:
        calculateBarWidth in class StackedBarRenderer
        Parameters:
        plot - the plot.
        dataArea - the data area.
        rendererIndex - the renderer index.
        state - the renderer state.
      • calculateBarW0

        protected double calculateBarW0​(CategoryPlot plot,
                                        PlotOrientation orientation,
                                        java.awt.geom.Rectangle2D dataArea,
                                        CategoryAxis domainAxis,
                                        CategoryItemRendererState state,
                                        int row,
                                        int column)
        Calculates the coordinate of the first "side" of a bar. This will be the minimum x-coordinate for a vertical bar, and the minimum y-coordinate for a horizontal bar.
        Overrides:
        calculateBarW0 in class BarRenderer
        Parameters:
        plot - the plot.
        orientation - the plot orientation.
        dataArea - the data area.
        domainAxis - the domain axis.
        state - the renderer state (has the bar width precalculated).
        row - the row index.
        column - the column index.
        Returns:
        The coordinate.
      • drawItem

        public void drawItem​(java.awt.Graphics2D g2,
                             CategoryItemRendererState state,
                             java.awt.geom.Rectangle2D dataArea,
                             CategoryPlot plot,
                             CategoryAxis domainAxis,
                             ValueAxis rangeAxis,
                             CategoryDataset dataset,
                             int row,
                             int column,
                             int pass)
        Draws a stacked bar for a specific item.
        Specified by:
        drawItem in interface CategoryItemRenderer
        Overrides:
        drawItem in class StackedBarRenderer
        Parameters:

      • equals

        public boolean equals​(java.lang.Object obj)
        Tests this renderer for equality with an arbitrary object.
        Overrides:
        equals in class StackedBarRenderer
        Parameters:
        obj - the object (null permitted).
        Returns:
        A boolean.
