public StackedAreaRenderer()
Creates a new renderer.

Method Details

drawItem

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.
Specified by:
drawItem in interface CategoryItemRenderer
Overrides:
drawItem in interface AreaRenderer
Parameters:
g2 - the graphics device.
state - the renderer state.
dataArea - the data plot area.
plot - the plot.
domainAxis - the domain axis.
rangeAxis - the range axis.
dataset - the data.
row - the row index (zero-based).
column - the column index (zero-based).
pass - the pass index.

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 AbstractCategoryItemRenderer
Parameters:
dataset - the dataset (null not permitted).
Returns:
The range (or null if the dataset is empty).

getPreviousHeight

protected double getPreviousHeight(CategoryDataset data,
                                   int series,
                                   int category)
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:
data - the data.
series - the series.
category - the category.
Returns:
double returns a cumulative value for all series' values up to but excluding series for Object category.
