Constructor Detail

### AbstractXYItemRenderer

    protected AbstractXYItemRenderer()

  Creates a renderer where the tooltip generator and the URL generator are both `null`.

Method Detail

### getPassCount

    public int getPassCount()

  Returns the number of passes through the data that the renderer requires in order to draw the chart. Most charts will require a single pass, but some require two passes.

  Specified by:
    `getPassCount` in interface `XYItemRenderer`
  Returns:
    The pass count.

### getPlot

    public XYPlot getPlot()

  Returns the plot that the renderer is assigned to.

  Specified by:
    `getPlot` in interface `XYItemRenderer`
  Returns:
    The plot (possibly `null`).

### setPlot

    public void setPlot(XYPlot plot)

  Sets the plot that the renderer is assigned to.

  Specified by:
    `setPlot` in interface `XYItemRenderer`
  Parameters:
    `plot` - the plot (`null` permitted).

### initialise

    public XYItemRendererState initialise(java.awt.Graphics2D g2,
                                          java.awt.geom.Rectangle2D dataArea,
                                          XYPlot plot,
                                          XYDataset data,
                                          PlotRenderingInfo info)

  Initialises the renderer and returns a state object that should be passed to all subsequent calls to the drawItem() method.

  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.

  Specified by:
    `initialise` in interface `XYItemRenderer`
  Parameters:
    `g2` - the graphics device.
    `dataArea` - the area inside the axes.
