public class StackedXYBarRenderer extends XYBarRenderer
A bar renderer that displays the series items stacked. The dataset used together with this renderer must be aIntervalXYDatasetand aTableXYDataset. For example, the dataset classCategoryTableXYDatasetimplements both interfaces. The example shown here is generated by theStackedXYBarChartDemo2.javaprogram included in the JFreeChart demo collection:

Method Detail
-
getRenderAsPercentages
public boolean getRenderAsPercentages()
Returnstrueif the renderer displays each item value as a percentage (so that the stacked bars add to 100%), andfalseotherwise.- Returns:
- A boolean.
- See Also:
setRenderAsPercentages(boolean)
-
setRenderAsPercentages
public void setRenderAsPercentages(boolean asPercentages)
Sets the flag that controls whether the renderer displays each item value as a percentage (so that the stacked bars add to 100%), and sends aRendererChangeEventto all registered listeners.- Parameters:
asPercentages- the flag.- See Also:
getRenderAsPercentages()
-
getPassCount
public int getPassCount()
Returns3to indicate that this renderer requires three passes for drawing (shadows are drawn in the first pass, the bars in the second, and item labels are drawn in the third pass so that they always appear in front of all the bars).- Specified by:
getPassCountin interfaceXYItemRenderer- Overrides:
getPassCountin classAbstractXYItemRenderer- Returns:
2.
-
initialise
public XYItemRendererState initialise(Graphics2D g2, Rectangle2D dataArea, XYPlot plot, XYDataset data, PlotRenderingInfo info)
Initialises the renderer and returns a state object that should be passed to all subsequent calls to the drawItem() method. Here there is nothing to do.- Specified by:
initialisein interfaceXYItemRenderer- Overrides:
initialisein classXYBarRenderer- Parameters:
g2- the graphics device.dataArea- the area inside the axes.plot- the plot.data- the data.info- an optional info collection object to return data back to the caller.- Returns:
- A state object.
-
findRangeBounds
public Range findRangeBounds(XYDataset dataset)
Returns the range of values the renderer requires to display all the items from the specified dataset.- Specified by:
findRangeBoundsin interfaceXYItemRenderer- Overrides:
findRangeBoundsin classXYBarRenderer- Parameters:
dataset- the dataset (nullpermitted).- Returns:
- The range (
nullif the dataset isnullor empty). - See Also:
AbstractXYItemRenderer.findDomainBounds(XYDataset)

drawItem
public void drawItem(Graphics2D g2, XYItemRendererState state, Rectangle2D dataArea, PlotRenderingInfo info, XYPlot plot, ValueAxis domainAxis, ValueAxis rangeAxis, XYDataset dataset, int series, int item, CrosshairState crosshairState, int pass)
Draws the visual representation of a single data item.- Specified by:
drawItemin interfaceXYItemRenderer- Overrides:
drawItemin classXYBarRenderer- Parameters:
g2- the graphics device.state- the renderer state.dataArea- the area within which the plot is being drawn.info- collects information about the drawing.plot- the plot (can be used to obtain standard color information etc).domainAxis- the domain axis.rangeAxis- the range axis.dataset- the dataset.series- the series index (zero-based).item- the item index (zero-based).crosshairState- crosshair information for the plot (nullpermitted).pass- the pass index.
-
equals
public boolean equals(Object obj)
Tests this renderer for equality with an arbitrary object.- Overrides:
equalsin classXYBarRenderer- Parameters:
obj- the object (nullpermitted).- Returns:
- A boolean.
-
hashCode
public int hashCode()
Returns a hash code for this instance.- Overrides:
hashCodein classAbstractXYItemRenderer- Returns:
