Constructor Details

MultiplePiePlot

public MultiplePiePlot()
Creates a new plot with no data.

MultiplePiePlot

public MultiplePiePlot(CategoryDataset dataset)
Creates a new plot.
Parameters:
dataset - the dataset (null permitted).

Method Details

draw

public void draw(Graphics2D g2,
                 Rectangle2D area,
                 Point2D anchor,
                 PlotState parentState,
                 PlotRenderingInfo info)
Draws the plot on a Java 2D graphics device (such as the screen or a printer).
Overrides:
draw in interface Plot
Parameters:
g2 - the graphics device.
area - the area within which the plot should be drawn.
anchor - the anchor point (null permitted).
parentState - the state from the parent plot, if there is one.
info - collects info about the drawing.

equals

public boolean equals(Object obj)
Tests this plot for equality with an arbitrary object. Note that the plot's dataset is not considered in the equality test.
Overrides:
equals in interface Plot
Parameters:
obj - the object (null permitted).
Returns:
true if this plot is equal to obj, and false otherwise.

getAggregatedItemsKey

public Comparable getAggregatedItemsKey()
Returns the key for aggregated items in the pie plots, if there are any. The default value is "Other".
Returns:
The aggregated items key.
Since:
1.0.2

getAggregatedItemsPaint

public Paint getAggregatedItemsPaint()
Returns the paint used to draw the pie section representing the aggregated items. The default value is Color.lightGray.
Returns:
The paint.
Since:
1.0.2

getDataExtractOrder

public TableOrder getDataExtractOrder()
Returns the data extract order (by row or by column).
Returns:
The data extract order (never null).

getDataset

public CategoryDataset getDataset()
Returns the dataset used by the plot.
Returns:
The dataset (possibly null).

getLegendItems

public LegendItemCollection getLegendItems()
Returns a collection of legend items for the pie chart.
Specified by:
getLegendItems in interface LegendItemSource
Overrides:
getLegendItems in interface Plot
Returns:
The legend items.

getLimit

public double getLimit()
Returns the limit (as a percentage) below which small pie sections are aggregated.
Returns:
The limit percentage.

getPieChart

public JFreeChart getPieChart()

Overrides:
getPlotType in interface Plot
Returns:
The plot type.

setAggregatedItemsKey

public void setAggregatedItemsKey(Comparable key)

Parameters:
key - the key (null not permitted).
Since:
1.0.2

setAggregatedItemsPaint

public void setAggregatedItemsPaint(Paint paint)
