Inherited Fields
From class org.jfree.chart.renderer.AbstractRenderer
Public Constructors
StackedXYAreaRenderer2()
Creates a new renderer.
StackedXYAreaRenderer2(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.
Range findRangeBounds(XYDataset dataset)
Returns the range of values the renderer requires to display all the items from the specified dataset.
int getPassCount()

Public Constructors

public StackedXYAreaRenderer2 ()

Creates a new renderer.

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).

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

public boolean equals (Object obj)

Tests this renderer for equality with an arbitrary object.

Parameters
obj the object (null permitted).
Returns
  • A boolean.

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).

public int getPassCount ()

Returns the number of passes required by the renderer.

Returns
  • 1.

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.

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.
