Constructor Detail

SamplingXYLineRenderer

public SamplingXYLineRenderer()
Creates a new renderer.

Method Detail

getLegendLine

public java.awt.Shape getLegendLine()
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)
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,
                                      XYPlot plot,
                                      XYDataset data,
                                      PlotRenderingInfo info)
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 plot.
data - the data.
info - an optional info collection object to return data back to the caller.
Returns:
The renderer state.

drawItem

public void drawItem(java.awt.Graphics2D g2,
                     XYItemRendererState state,
                     java.awt.geom.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.

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.

getLegendItem

public LegendItem getLegendItem(int datasetIndex,
                                int series)
Returns a legend item for the specified series.

Specified by:
getLegendItem in interface XYItemRenderer
Overrides:
getLegendItem in class AbstractXYItemRenderer
Parameters:
datasetIndex - the dataset index (zero-based).
series - the series index (zero-based).
Returns:
A legend item for the series.

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.
