public class SamplingXYLineRenderer
- extends AbstractXYItemRenderer
- implements XYItemRenderer, java.lang.Cloneable, org.jfree.util.PublicCloneable, java.io.Serializable
A renderer that draws line charts. The renderer doesn't necessarily plot
every data item - instead, it tries to plot only those data items that
make a difference to the visual output (the other data items are skipped).
This renderer is designed for use with the XYPlot
class.

- 1.0.13

SamplingXYLineRenderer
public SamplingXYLineRenderer()
- Creates a new renderer.
getLegendLine
public java.awt.Shape getLegendLine()
- Deprecated. As of version 1.0.14, this method is deprecated. You
should use the
AbstractRenderer.getBaseLegendShape()
method instead.
- Returns the shape used to represent a line in the legend.
- Returns:
- The legend line (never
null
). - See Also:
setLegendLine(Shape)
setLegendLine
public void setLegendLine(java.awt.Shape line)
- Deprecated. As of version 1.0.14, this method is deprecated. You should
use the
AbstractRenderer.setBaseLegendShape(java.awt.Shape)
method instead.
- Sets the shape used as a line in each legend item and sends a
RendererChangeEvent
to all registered listeners.
- Parameters:
line
- the line (null
not permitted).- See Also:
getLegendLine()
getPassCount
public int getPassCount()
- Returns the number of passes through the data that the renderer requires
in order to draw the chart. Most charts will require a single pass, but
some require two passes.
- Specified by:
getPassCount
in interface XYItemRenderer
- Overrides:
getPassCount
in class AbstractXYItemRenderer
- Returns:
- The pass count.
initialise
public XYItemRendererState initialise(java.awt.Graphics2D g2,
java.awt.geom.Rectangle2D dataArea,

- Initialises the renderer.
This method will be called before the first item is rendered, giving the
renderer an opportunity to initialise any state information it wants to
maintain. The renderer can do nothing if it chooses.
- Specified by:
initialise
in interface XYItemRenderer
- Overrides:
initialise
in class AbstractXYItemRenderer
- Parameters:
g2
- the graphics device.dataArea
- the area inside the axes.plot

- the data.info
- an optional info collection object to return data back to
the caller.
- Returns:
- The renderer state.

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.
- Specified by:
drawItem
in interface XYItemRenderer
- 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.
clone
public java.lang.Object clone()
throws java.lang.CloneNotSupportedException
- Returns a clone of the renderer.
- Specified by:
clone
in interface org.jfree.util.PublicCloneable
- Overrides:
clone
in class AbstractXYItemRenderer
- Returns:
- A clone.
- Throws:
java.lang.CloneNotSupportedException
- if the clone cannot be created.
equals
public boolean equals(java.lang.Object obj)
- Tests this renderer for equality with an arbitrary object.
- Overrides:
equals
in class AbstractXYItemRenderer
- Parameters:
obj
- the object (null
permitted).

true
or false
.
