Constructor Detail

XYSplineRenderer

public XYSplineRenderer()
Creates a new instance with the 'precision' attribute defaulting to 5.


XYSplineRenderer

public XYSplineRenderer(int precision)
Creates a new renderer with the specified precision.

Parameters:
precision - the number of points between data items.
Method Detail

getPrecision

public int getPrecision()
Get the resolution of splines.

Returns:
Number of line segments between points.
See Also:
setPrecision(int)

setPrecision

public void setPrecision(int p)
Set the resolution of splines and sends a RendererChangeEvent to all registered listeners.

Parameters:
p - number of line segments between points (must be > 0).
See Also:
getPrecision()

initialise

public org.jfree.chart.renderer.xy.XYItemRendererState initialise(java.awt.Graphics2D g2,
                                                                  java.awt.geom.Rectangle2D dataArea,
                                                                  org.jfree.chart.plot.XYPlot plot,
                                                                  org.jfree.data.xy.XYDataset data,
                                                                  org.jfree.chart.plot.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 org.jfree.chart.renderer.xy.XYItemRenderer
Overrides:
initialise in class org.jfree.chart.renderer.xy.XYLineAndShapeRenderer
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.

drawPrimaryLineAsPath

protected void drawPrimaryLineAsPath(org.jfree.chart.renderer.xy.XYItemRendererState state,
                                     java.awt.Graphics2D g2,
                                     org.jfree.chart.plot.XYPlot plot,
                                     org.jfree.data.xy.XYDataset dataset,
                                     int pass,
                                     int series,
                                     int item,
                                     org.jfree.chart.axis.ValueAxis domainAxis,
                                     org.jfree.chart.axis.ValueAxis rangeAxis,
                                     java.awt.geom.Rectangle2D dataArea)
Draws the item (first pass). This method draws the lines connecting the items. Instead of drawing separate lines, a GeneralPath is constructed and drawn at the end of the series painting.

Overrides:
drawPrimaryLineAsPath in class org.jfree.chart.renderer.xy.XYLineAndShapeRenderer
Parameters:
g2 - the graphics device.
state - the renderer state.
plot - the plot (can be used to obtain standard color information etc).
dataset - the dataset.
pass - the pass.
series - the series index (zero-based).
item - the item index (zero-based).
domainAxis - the domain axis.
rangeAxis - the range axis.
dataArea - the area within which the data is being drawn.

equals

public boolean equals(java.lang.Object obj)
Tests this renderer for equality with an arbitrary object.

Overrides:
equals in class XYConditionRenderer
Parameters:
obj - the object (null permitted).
Returns:
A boolean.

hashCode

public int hashCode()
Overrides:
hashCode in class XYConditionRenderer
