public interface CategoryItemRenderer
extends LegendItemSource

A plug-in object that is used by the CategoryPlot class to display individual data items from a CategoryDataset.

This interface defines the methods that must be provided by all renderers. If you are implementing a custom renderer, you should consider extending the AbstractCategoryItemRenderer class.

Most renderer attributes are defined using a two layer approach. When looking up an attribute (for example, the outline paint) the renderer first checks to see if there is a setting that applies to a specific series that the renderer draws. If there is, that setting is used, but if it is null the renderer looks up the default setting. Some attributes allow the base setting to be null, while other attributes enforce non-null values.

getLegendItems

Method Details

getPassCount

int getPassCount()

Returns the number of passes through the dataset required by the renderer. Usually this will be one, but some renderers may use a second or third pass to overlay items on top of things that were drawn in an earlier pass.

Returns:

The pass count.

getPlot

CategoryPlot getPlot()

Returns the plot that the renderer has been assigned to (where null indicates that the renderer is not currently assigned to a plot).

Returns:

The plot (possibly null).

See Also:

• setPlot(CategoryPlot)

setPlot

void setPlot(CategoryPlot plot)

Sets the plot that the renderer has been assigned to. This method is usually called by the CategoryPlot, in normal usage you shouldn't need to call this method directly.

Parameters:

plot - the plot (null not permitted).

See Also:

• getPlot()

addChangeListener

void addChangeListener(RendererChangeListener listener)

Adds a change listener.

Parameters:

listener - the listener.

See Also:

findRangeBounds

Range findRangeBounds(CategoryDataset dataset)

Returns the range of values the renderer requires to display all the items from the specified dataset.

initialise

CategoryItemRendererState initialise(Graphics2D g2,
 Rectangle2D dataArea,
 CategoryPlot plot,
