Constructor Summary | |
---|---|
XYAreaRenderer()
Constructs a new renderer. | |
XYAreaRenderer(int type)
Constructs a new renderer.
| |
XYAreaRenderer(int type, XYToolTipGenerator toolTipGenerator, XYURLGenerator urlGenerator)
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.
|
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 | getPlotArea()
Returns true if Area is being plotted by the renderer.
|
boolean | getPlotLines()
Returns true if lines are being plotted by the renderer.
|
boolean | getPlotShapes()
Returns true if shapes are being plotted by the renderer.
|
XYItemRendererState | initialise(Graphics2D g2, Rectangle2D dataArea, XYPlot plot, XYDataset data, PlotRenderingInfo info)
Initialises the renderer and returns a state object that should be
passed to all subsequent calls to the drawItem() method.
|
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.
|

Parameters: type the type of renderer. toolTipGenerator the tool tip generator to use
(null
permitted). urlGenerator the URL generator (null
permitted).
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 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.
Parameters: obj the object (null
permitted).
Returns: A boolean.
Returns: The legend area (never null
).
Parameters: datasetIndex the dataset index (zero-based). series the series index (zero-based).
Returns: A legend item for the series.
Returns: true
if Area is being plotted by the renderer.
Returns: true
if lines are being plotted by the renderer.
Returns: true
if shapes are being plotted by the renderer.
Parameters: g2 the graphics device. dataArea the area inside the axes. plot the plot. data the data. info an optional info collection object to return data back to the caller.
Returns: A state object for use by the renderer.
Returns: The flag.
