Class PiePlot3D

public class PiePlot3D extends PiePlot implements Serializable

A plot that displays data in the form of a 3D pie chart, using data from any class that implements the PieDataset interface.

Although this class extends PiePlot, it does not currently support exploded sections.

Constructor Summary
PiePlot3D()
Creates a new instance with no dataset.
PiePlot3D(PieDataset dataset)
Creates a pie chart with a three dimensional effect using the specified dataset.
Method Summary
voiddraw(Graphics2D g2, Rectangle2D plotArea, Point2D anchor, PlotState parentState, PlotRenderingInfo info)
Draws the plot on a Java 2D graphics device (such as the screen or a printer).
protected voiddrawSide(Graphics2D g2, Rectangle2D plotArea, Arc2D arc, Area front, Area back, Paint paint, Paint outlinePaint, Stroke outlineStroke, boolean drawFront, boolean drawBack)
Draws the side of a pie section.
booleanequals(Object obj)
Tests this plot for equality with an arbitrary object.
doublegetDepthFactor()
Returns the depth factor for the chart.
StringgetPlotType()
Returns a short string describing the type of plot.
voidsetDepthFactor(double factor)
Sets the pie depth as a percentage of the height of the plot area, and sends a PlotChangeEvent to all registered listeners.

Constructor Detail

PiePlot3D

public PiePlot3D()
Creates a new instance with no dataset.

PiePlot3D

public PiePlot3D(PieDataset dataset)
Creates a pie chart with a three dimensional effect using the specified dataset.

Parameters: dataset the dataset (null permitted).

Method Detail

draw

public void draw(Graphics2D g2, Rectangle2D plotArea, Point2D anchor, PlotState parentState, PlotRenderingInfo info)
Draws the plot on a Java 2D graphics device (such as the screen or a printer). This method is called by the JFreeChart class, you don't normally need to call it yourself.

Parameters: g2 the graphics device. plotArea the area within which the plot should be drawn. anchor the anchor point. parentState the state from the parent plot, if there is one. info collects info about the drawing (null permitted).

drawSide

protected void drawSide(Graphics2D g2, Rectangle2D plotArea, Arc2D arc, Area front, Area back, Paint paint, Paint outlinePaint, Stroke outlineStroke, boolean drawFront, boolean drawBack)
Draws the side of a pie section.

Parameters: g2 the graphics device. plotArea the plot area. arc the arc. front the front of the pie. back the back of the pie. paint the color. outlinePaint the outline paint. outlineStroke the outline stroke. drawFront draw the front? drawBack draw the back?

equals

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

Parameters: obj the object (null permitted).

Returns: A boolean.

getDepthFactor

public double getDepthFactor()
Returns the depth factor for the chart.

Returns: The depth factor.

getPlotType

public String getPlotType()
Returns a short string describing the type of plot.

Returns: Pie 3D Plot.

setDepthFactor

public void setDepthFactor(double factor)
Sets the pie depth as a percentage of the height of the plot area, and sends a PlotChangeEvent to all registered listeners.

Parameters: factor the depth factor (for example, 0.20 is twenty percent).
