Interface CategoryItemRenderer

All Superinterfaces:
  LegendItemSource

All Known Implementing Classes:

    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 "three layer" approach. When looking up an attribute (for example, the outline paint) the renderer first checks to see if there is a setting (in layer 0) that applies to ALL items that the renderer draws. If there is, that setting is used, but if it is `null` the renderer looks up the next layer, which contains "per series" settings for the attribute (many attributes are defined on a per series basis, so this is the layer that is most commonly used). If the layer 1 setting is `null`, the renderer will look up the final layer, which provides a default or "base" setting. Some attributes allow the base setting to be `null`, while other attributes enforce non-`null` values.

`getLegendItems`

Method Detail

### 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:
    `removeChangeListener(RendererChangeListener)`

### removeChangeListener

    void removeChangeListener(RendererChangeListener listener)

  Removes a change listener.

  Parameters:
    `listener` - the listener.
  See Also:
    `addChangeListener(RendererChangeListener)`

### findRangeBounds

    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` permitted).
  Returns:
    The range (or `null` if the dataset is `null` or empty).

### initialise

    CategoryItemRendererState initialise(java.awt.Graphics2D g2,

  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. The renderer can do nothing if it chooses.

  Parameters:
