Creates a new renderer.

Method Details

calculateBarW0

protected double calculateBarW0(CategoryPlot plot,
                                PlotOrientation orientation,
                                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 interface 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.

calculateBarWidth

protected void calculateBarWidth(CategoryPlot plot,
                                 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 interface StackedBarRenderer
Parameters:
plot - the plot.
dataArea - the data area.
rendererIndex - the renderer index.
state - the renderer state.

drawItem

public void drawItem(Graphics2D g2,
                     CategoryItemRendererState state,
                     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 interface StackedBarRenderer
Parameters:
g2 - the graphics device.
state - the renderer state.
dataArea - the plot area.
plot - the plot.
domainAxis - the domain (category) axis.
rangeAxis - the range (value) axis.
dataset - the data.
row - the row index (zero-based).
column - the column index (zero-based).
pass - the pass index.

equals

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

findRangeBounds

public Range findRangeBounds(CategoryDataset dataset)
Returns the range of values the renderer requires to display all the items from the specified dataset.
Specified by:
findRangeBounds in interface CategoryItemRenderer
Overrides:
findRangeBounds in interface StackedBarRenderer
Parameters:
dataset - the dataset (null permitted).
Returns:
The range (or null if the dataset is null or empty).

setSeriesToGroupMap

public void setSeriesToGroupMap(KeyToGroupMap map)
Updates the map used to assign each series to a group.
Parameters:
map - the map (null not permitted).
