public class StackedXYAreaRenderer2 extends XYAreaRenderer2 implements Cloneable, PublicCloneable, Serializable

A stacked area renderer for the XYPlot class.
Constructor Summary
StackedXYAreaRenderer2()
Creates a new renderer.
StackedXYAreaRenderer2(XYToolTipGenerator labelGenerator, XYURLGenerator urlGenerator)
Constructs a new renderer.
Method Summary
Objectclone()
Returns a clone of the renderer.
voiddrawItem(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.
booleanequals(Object obj)
Tests this renderer for equality with an arbitrary object.
RangefindRangeBounds(XYDataset dataset)
Returns the range of values the renderer requires to display all the items from the specified dataset.
intgetPassCount()
Returns the number of passes required by the renderer.
booleangetRoundXCoordinates()
Returns the flag that controls whether or not the x-coordinates (in Java2D space) are rounded to integer values.
voidsetRoundXCoordinates(boolean round)
Sets the flag that controls whether or not the x-coordinates (in Java2D space) are rounded to integer values, and sends a RendererChangeEvent to all registered listeners.

Constructor Detail

StackedXYAreaRenderer2

public StackedXYAreaRenderer2()
Creates a new renderer.

StackedXYAreaRenderer2

public StackedXYAreaRenderer2(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

clone

public Object clone()
Returns a clone of the renderer.

Returns: A clone.

Throws: CloneNotSupportedException if the renderer cannot be cloned.

drawItem

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 information about crosshairs on a plot. pass the pass index.

equals

public boolean equals(Object obj)
Tests this renderer for equality with an arbitrary object.

Parameters: obj the object (null permitted).

Returns: A boolean.

findRangeBounds

public Range findRangeBounds(XYDataset 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).

getPassCount

public int getPassCount()
Returns the number of passes required by the renderer.

Returns: 1.

getRoundXCoordinates

public boolean getRoundXCoordinates()
Returns the flag that controls whether or not the x-coordinates (in Java2D space) are rounded to integer values.

Returns: The flag.

Since: 1.0.4

setRoundXCoordinates

public void setRoundXCoordinates(boolean round)
Sets the flag that controls whether or not the x-coordinates (in Java2D space) are rounded to integer values, and sends a RendererChangeEvent to all registered listeners.

Parameters: round the new flag value.

Since: 1.0.4
