Class XYDotRenderer

public class XYDotRenderer extends AbstractXYItemRenderer implements XYItemRenderer, Cloneable, PublicCloneable, Serializable

A renderer that draws a small dot at each data point for an XYPlot.
Constructor Summary
XYDotRenderer()
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.
intgetDotHeight()
Returns the dot height (the default value is 1).
intgetDotWidth()
Returns the dot width (the default value is 1).
voidsetDotHeight(int h)
Sets the dot height and sends a RendererChangeEvent to all registered listeners.
voidsetDotWidth(int w)
Sets the dot width and sends a RendererChangeEvent to all registered listeners.

Constructor Detail

XYDotRenderer

public XYDotRenderer()
Constructs a new renderer.

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 (horizontal) axis. rangeAxis the range (vertical) 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.

equals

public boolean equals(Object obj)
Tests this renderer for equality with an arbitrary object. This method returns true if and only if:

Parameters: obj the object (null permitted).

Returns: A boolean.

getDotHeight

public int getDotHeight()
Returns the dot height (the default value is 1).

Returns: The dot height.

Since: 1.0.2

getDotWidth

public int getDotWidth()
Returns the dot width (the default value is 1).

Returns: The dot width.

Since: 1.0.2

setDotHeight

public void setDotHeight(int h)
Sets the dot height and sends a RendererChangeEvent to all registered listeners.

Parameters: h the new height (must be greater than zero).

Throws: IllegalArgumentException if h is less than one.

Since: 1.0.2

See Also: getDotHeight

setDotWidth

public void setDotWidth(int w)
Sets the dot width and sends a RendererChangeEvent to all registered listeners.

Parameters: w the new width (must be greater than zero).

Throws: IllegalArgumentException if w is less than one.

Since: 1.0.2
