Inherited Fields
From class org.jfree.chart.renderer.AbstractRenderer
Public Constructors
XYAreaRenderer2()
Constructs a new renderer.
XYAreaRenderer2(XYToolTipGenerator labelGenerator, XYURLGenerator urlGenerator)
Constructs a new renderer.
Public Methods
Object clone()
Returns a clone of the renderer.
void drawItem(Graphics2D g2, XYItemRendererState state, Rectangle2D dataArea, PlotRenderingInfo info, XYPlot plot, ValueAxis domainAxis, ValueAxis rangeAxis, XYDataset dataset, int series, int item, CrosshairState crosshairState, int pass)
Draws the visual representation of a single data item.
boolean equals(Object obj)
Tests this renderer for equality with an arbitrary object.
Shape getLegendArea()
Returns the shape used to represent an area in the legend.
LegendItem getLegendItem(int datasetIndex, int series)
Returns a default legend item for the specified series.
boolean getPlotLines()
This method is deprecated. This method was included in the API by mistake and serves no useful purpose. It has always returned false.
boolean isOutline()
Returns a flag that controls whether or not outlines of the areas are drawn.
void setLegendArea(Shape area)
Sets the shape used as an area in each legend item and sends a RendererChangeEvent to all registered listeners.
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.

Public Constructors

public XYAreaRenderer2 ()

Constructs a new renderer.

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).

Public Methods

public Object clone ()

Returns a clone of the renderer.

Returns
  • A clone.
Throws
CloneNotSupportedException if the renderer cannot be cloned.

public void drawItem (Graphics2D g2, XYItemRendererState state, Rectangle2D dataArea, PlotRenderingInfo info, XYPlot plot, ValueAxis domainAxis, ValueAxis rangeAxis, XYDataset dataset, int series, int item, CrosshairState crosshairState, int pass)

Draws the visual representation of a single data item.

Parameters
g2 the graphics device.
state the renderer state.
dataArea the area within which the data is being drawn.
info collects information about the drawing.
plot the plot (can be used to obtain standard color information etc).
domainAxis the domain axis.
rangeAxis the range axis.
dataset the dataset.
series the series index (zero-based).
item the item index (zero-based).
crosshairState crosshair information for the plot (null permitted).
pass the pass index.

public boolean equals (Object obj)

Tests this renderer for equality with an arbitrary object.

Parameters
obj the object (null not permitted).
Returns
  • A boolean.

public Shape getLegendArea ()

Returns the shape used to represent an area in the legend.

Returns
  • The legend area (never null).

public LegendItem getLegendItem (int datasetIndex, int series)

Returns a default legend item for the specified series. Subclasses should override this method to generate customised items.

Parameters
datasetIndex the dataset index (zero-based).
series the series index (zero-based).
Returns
  • A legend item for the series.

public boolean getPlotLines ()

This method is 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.

public boolean isOutline ()

Returns a flag that controls whether or not outlines of the areas are drawn.

Returns
  • The flag.

public void setLegendArea (Shape area)

Sets the shape used as an area in each legend item and sends a RendererChangeEvent to all registered listeners.

Parameters
area the area (null not permitted).

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.
