Constructor Summary | |
---|---|
XYDotRenderer()
Constructs a new renderer. |
Method Summary | |
---|---|
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. |
int | getDotHeight()
Returns the dot height (the default value is 1).
|
int | getDotWidth()
Returns the dot width (the default value is 1).
|
LegendItem | getLegendItem(int datasetIndex, int series)
Returns a legend item for the specified series.
|
Shape | getLegendShape()
Returns the shape used to represent an item in the legend.
|
void | setDotHeight(int h)
Sets the dot height and sends a RendererChangeEvent to all
registered listeners.
|
void | setDotWidth(int w)
Sets the dot width and sends a RendererChangeEvent to all
registered listeners.
|
void | setLegendShape(Shape shape)
Sets the shape used as a line in each legend item and sends a
RendererChangeEvent to all registered listeners.

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