XYAreaRenderer2

public XYAreaRenderer2()
Constructs a new renderer.


XYAreaRenderer2

public XYAreaRenderer2(XYToolTipGenerator labelGenerator,
                       XYURLGenerator urlGenerator)
Constructs a new renderer.

Parameters:
labelGenerator - the tool tip generator to use. null is none.
urlGenerator - the URL generator (null permitted).
Method Detail

isOutline

public boolean isOutline()
Returns a flag that controls whether or not outlines of the areas are drawn.

Returns:
The flag.
See Also:

public void setOutline(boolean show)
Sets a flag that controls whether or not outlines of the areas are drawn, and sends a RendererChangeEvent to all registered listeners.

Parameters:
show - the flag.
See Also:
isOutline()

getPlotLines

public boolean getPlotLines()
Deprecated. This method was included in the API by mistake and serves no useful purpose. It has always returned false.

This method should not be used.

Returns:
false always.
