Initialises the renderer then returns the number of 'passes' through the data that the renderer will require (usually just one). 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:
g2 - the graphics device.

axis - the value axis.
dataArea - the area for plotting data (not yet adjusted for any 3D effect).
value - the value.
paint - the paint (null not permitted).
stroke - the stroke (null not permitted).

drawDomainMarker

                             XYPlot plot,
                             ValueAxis axis,
                             Marker marker,
                             java.awt.geom.Rectangle2D dataArea)
Draws the specified marker against the domain axis.

Parameters:
g2 - the graphics device.
plot - the plot.
axis - the value axis.
marker - the marker.
dataArea - the axis data area.

drawRangeMarker

public void drawRangeMarker(java.awt.Graphics2D g2,
                            XYPlot plot,
                            ValueAxis axis,

                            java.awt.geom.Rectangle2D dataArea)
Draws a horizontal line across the chart to represent a 'range marker'.

Parameters:
g2 - the graphics device.
plot - the plot.
axis - the value axis.
marker - the marker line.
dataArea - the axis data area.

getPlot

public XYPlot getPlot()
Returns the plot that this renderer has been assigned to.

Returns:
the plot.

setPlot

public void setPlot(XYPlot plot)
Sets the plot that this renderer is assigned to. This method will be called by the plot class...you do not need to call it yourself.

Parameters:
plot - the plot.

findDomainBounds

public Range findDomainBounds(XYDataset dataset)
Returns the lower and upper bounds (range) of the x-values in the specified dataset.

Parameters:
dataset - the dataset (null permitted).
Returns:
The range.

findRangeBounds

public Range findRangeBounds(XYDataset dataset)
Returns the lower and upper bounds (range) of the y-values in the specified dataset. The implementation of this method will take into account the presentation used by the renderers (for example, a renderer that "stacks" values will return a bigger range than a renderer that doesn't.

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

addChangeListener

public void addChangeListener(RendererChangeListener listener)
Add a renderer change listener.

Parameters:
listener - the listener.

removeChangeListener

public void removeChangeListener(RendererChangeListener listener)
Removes a change listener.

Parameters:
listener - the listener.
