SPECIAL NOTE: This renderer does not currently handle negative data values correctly. This should get fixed at some point, but the current workaround is to use the StackedXYAreaRenderer2 class instead.

Parameters:   dataset - the dataset (null permitted). public  int getPassCount()      Returns the number of passes required by the renderer. protected  double getPreviousHeight(TableXYDataset dataset, int series, int index)      Calculates the stacked value of the all series up to, but not including series for the specified item. public  Paint getShapePaint()      Returns the paint used for rendering shapes, or null if using series paints. public  Stroke getShapeStroke()      Returns the stroke used for rendering shapes, or null if using series strokes. public  XYItemRendererState initialise(Graphics2D g2, Rectangle2D dataArea, XYPlot plot, XYDataset data, PlotRenderingInfo info)      Initialises the renderer. public  void setShapePaint(Paint shapePaint)      Sets the paint for rendering shapes and sends a RendererChangeEvent to all registered listeners. public  void setShapeStroke(Stroke shapeStroke)      Sets the stroke for rendering shapes and sends a RendererChangeEvent to all registered listeners. Constructor Detail StackedXYAreaRenderer public StackedXYAreaRenderer()(Code) Creates a new renderer. StackedXYAreaRenderer public StackedXYAreaRenderer(int type)(Code) Constructs a new renderer. Parameters:   type - the type of the renderer. StackedXYAreaRenderer public StackedXYAreaRenderer(int type, XYToolTipGenerator labelGenerator, XYURLGenerator urlGenerator)(Code) Constructs a new renderer. To specify the type of renderer, use one of the constants: SHAPES, LINES, SHAPES_AND_LINES, AREA or AREA_AND_SHAPES. Parameters:   type - the type of renderer. Parameters:   labelGenerator - the tool tip generator to use (null is none). Parameters:   urlGenerator - the URL generator (null permitted). Method Detail clone public Object clone() throws CloneNotSupportedException(Code) Returns a clone of the renderer. A clone. throws:   CloneNotSupportedException - if the renderer cannot be cloned. 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)(Code) Draws the visual representation of a single data item. Parameters:   g2 - the graphics device. Parameters:   state - the renderer state. Parameters:   dataArea - the area within which the data is being drawn. Parameters:   info - collects information about the drawing. Parameters:   plot - the plot (can be used to obtain standard color information etc). Parameters:   domainAxis - the domain axis. Parameters:   rangeAxis - the range axis. Parameters:   dataset - the dataset. Parameters:   series - the series index (zero-based). Parameters:   item - the item index (zero-based). Parameters:   crosshairState - information about crosshairs on a plot. Parameters:   pass - the pass index. throws:   ClassCastException - if state is not an instance ofStackedXYAreaRendererState or datasetis not an instance of TableXYDataset. equals public boolean equals(Object obj)(Code) Tests the renderer for equality with an arbitrary object. Parameters:   obj - the object (null permitted). A boolean. findRangeBounds public Range findRangeBounds(XYDataset dataset)(Code) Returns the range of values the renderer requires to display all the items from the specified dataset. Parameters:   dataset - the dataset (null permitted). The range ([0.0, 0.0] if the dataset contains no values, and null if the dataset is null). throws:   ClassCastException - if dataset is not an instanceof TableXYDataset. getPassCount public int getPassCount()(Code) Returns the number of passes required by the renderer. 2. getPreviousHeight protected double getPreviousHeight(TableXYDataset dataset, int series, int index)(Code) Calculates the stacked value of the all series up to, but not including series for the specified item. It returns 0.0 if series is the first series, i.e. 0. Parameters:   dataset - the dataset. Parameters:   series - the series. Parameters:   index - the index. The cumulative value for all series' values up to but excluding series for index. getShapePaint public Paint getShapePaint()(Code) Returns the paint used for rendering shapes, or null if using series paints. The paint (possibly null). See Also:   StackedXYAreaRenderer.setShapePaint(Paint) getShapeStroke public Stroke getShapeStroke()(Code) Returns the stroke used for rendering shapes, or null if using series strokes. The stroke (possibly null). See Also:   StackedXYAreaRenderer.setShapeStroke(Stroke) initialise public XYItemRendererState initialise(Graphics2D g2, Rectangle2D dataArea, XYPlot plot, XYDataset data, PlotRenderingInfo info)(Code) Initialises the renderer. This method will be called before the first item is rendered, giving the renderer an opportunity to initialise any state information it wants to maintain. Parameters:   g2 - the graphics device. Parameters:   dataArea - the area inside the axes. Parameters:   plot - the plot. Parameters:   data - the data. Parameters:   info - an optional info collection object to return data back to the caller. A state object that should be passed to subsequent calls to the drawItem() method. setShapePaint public void setShapePaint(Paint shapePaint)(Code) Sets the paint for rendering shapes and sends a RendererChangeEvent to all registered listeners. Parameters:   shapePaint - the paint (null permitted). See Also:   StackedXYAreaRenderer.getShapePaint() setShapeStroke public void setShapeStroke(Stroke shapeStroke)(Code) Sets the stroke for rendering shapes and sends a RendererChangeEvent to all registered listeners. Parameters:   shapeStroke - the stroke (null permitted).
