Constructor Summary public   StackedAreaRenderer()      Creates a new renderer. public   StackedAreaRenderer(boolean renderAsPercentages)      Creates a new renderer. Method Summary public  void drawItem(Graphics2D g2, CategoryItemRendererState state, Rectangle2D dataArea, CategoryPlot plot, CategoryAxis domainAxis, ValueAxis rangeAxis, CategoryDataset dataset, int row, int column, int pass)      Draw a single data item. public  boolean equals(Object obj)      Checks this instance for equality with an arbitrary object. Parameters:   obj - the object (null not permitted). public  Range findRangeBounds(CategoryDataset dataset)      Returns the range of values the renderer requires to display all the items from the specified dataset. Parameters:   dataset - the dataset (null not permitted). public  int getPassCount()      Returns the number of passes (2) required by this renderer. protected  double getPreviousHeight(CategoryDataset dataset, int series, int category)      Calculates the stacked value of the all series up to, but not including series for the specified category, category. public  boolean getRenderAsPercentages()      Returns true if the renderer displays each item value as a percentage (so that the stacked areas add to 100%), and false otherwise. protected  double[] getStackValues(CategoryDataset dataset, int series, int index)      Calculates the stacked values (one positive and one negative) of all series up to, but not including, series for the specified item. public  void setRenderAsPercentages(boolean asPercentages)      Sets the flag that controls whether the renderer displays each item value as a percentage (so that the stacked areas add to 100%), and sends a RendererChangeEvent to all registered listeners. Constructor Detail StackedAreaRenderer public StackedAreaRenderer()(Code) Creates a new renderer. StackedAreaRenderer public StackedAreaRenderer(boolean renderAsPercentages)(Code) Creates a new renderer. Parameters:   renderAsPercentages - a flag that controls whether the data valuesare rendered as percentages. Method Detail drawItem public void drawItem(Graphics2D g2, CategoryItemRendererState state, Rectangle2D dataArea, CategoryPlot plot, CategoryAxis domainAxis, ValueAxis rangeAxis, CategoryDataset dataset, int row, int column, int pass)(Code) Draw a single data item. Parameters:   g2 - the graphics device. Parameters:   state - the renderer state. Parameters:   dataArea - the data plot area. Parameters:   plot - the plot. Parameters:   domainAxis - the domain axis. Parameters:   rangeAxis - the range axis. Parameters:   dataset - the data. Parameters:   row - the row index (zero-based). Parameters:   column - the column index (zero-based). Parameters:   pass - the pass index. equals public boolean equals(Object obj)(Code) Checks this instance for equality with an arbitrary object. Parameters:   obj - the object (null not permitted). A boolean. findRangeBounds public Range findRangeBounds(CategoryDataset dataset)(Code) Returns the range of values the renderer requires to display all the items from the specified dataset. Parameters:   dataset - the dataset (null not permitted). The range (or null if the dataset is empty). getPassCount public int getPassCount()(Code) Returns the number of passes (2) required by this renderer. The first pass is used to draw the bars, the second pass is used to draw the item labels (if visible). The number of passes required by the renderer. getPreviousHeight protected double getPreviousHeight(CategoryDataset dataset, int series, int category)(Code) Calculates the stacked value of the all series up to, but not including series for the specified category, category. It returns 0.0 if series is the first series, i.e. 0. Parameters:   dataset - the dataset (null not permitted). Parameters:   series - the series. Parameters:   category - the category. double returns a cumulative value for all series' values up to but excluding series for Object category. getRenderAsPercentages public boolean getRenderAsPercentages()(Code) Returns true if the renderer displays each item value as a percentage (so that the stacked areas add to 100%), and false otherwise. A boolean. since:    1.0.3 getStackValues protected double[] getStackValues(CategoryDataset dataset, int series, int index)(Code) Calculates the stacked values (one positive and one negative) of all series up to, but not including, series for the specified item. It returns [0.0, 0.0] if series is the first series. Parameters:   dataset - the dataset (null not permitted). Parameters:   series - the series index. Parameters:   index - the item index. An array containing the cumulative negative and positive valuesfor all series values up to but excluding series for index. setRenderAsPercentages public void setRenderAsPercentages(boolean asPercentages)(Code) Sets the flag that controls whether the renderer displays each item value as a percentage (so that the stacked areas add to 100%), and sends a RendererChangeEvent to all registered listeners. Parameters:   asPercentages - the flag. since:    1.0.3 Methods inherited from org.jfree.chart.renderer.category.AreaRenderer public Object clone() throws CloneNotSupportedException(Code)(Java Doc)
