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

getDataset

public CategoryDataset getDataset()

Returns the dataset used by the plot.

Returns:

The dataset (possibly null).

setDataset

public void setDataset(CategoryDataset dataset)

Sets the dataset used by the plot and sends a PlotChangeEvent to all registered listeners.

Parameters:

dataset - the dataset (null permitted).

getPieChart

public JFreeChart getPieChart()

Returns the pie chart that is used to draw the individual pie plots. Note that there are some attributes on this chart instance that will be ignored at rendering time (for example, legend item settings).

Returns:

The pie chart (never null).

See Also:

• setPieChart(JFreeChart)

setPieChart

public void setPieChart(JFreeChart pieChart)

Sets the chart that is used to draw the individual pie plots. The chart's plot must be an instance of PiePlot.

Parameters:

pieChart - the pie chart (null not permitted).

See Also:

• getPieChart()

getDataExtractOrder

public TableOrder getDataExtractOrder()

Returns the data extract order (by row or by column).

Returns:

The data extract order (never null).

setDataExtractOrder

public void setDataExtractOrder(TableOrder order)

Sets the data extract order (by row or by column) and sends a PlotChangeEvent to all registered listeners.

Parameters:

order - the order (null not permitted).

getLimit

public double getLimit()

Returns the limit (as a percentage) below which small pie sections are aggregated.

Returns:

The limit percentage.

setLimit

public void setLimit(double limit)

Sets the limit below which pie sections are aggregated. Set this to 0.0 if you don't want any aggregation to occur.

Parameters:

limit - the limit percent.

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.

setAggregatedItemsKey

public void setAggregatedItemsKey(Comparable key)

Sets the key for aggregated items in the pie plots. You must ensure that this doesn't clash with any keys in the dataset.

Parameters:

key - the key (null not permitted).

getAggregatedItemsPaint

public Paint getAggregatedItemsPaint()

Returns the paint used to draw the pie section representing the aggregated items. The default value is {code Color.LIGHT_GRAY}.

Returns:

The paint.

setAggregatedItemsPaint

public void setAggregatedItemsPaint(Paint paint)

Sets the paint used to draw the pie section representing the aggregated items and sends a PlotChangeEvent to all registered listeners.

Parameters:

paint - the paint (null not permitted).

getPlotType

public String getPlotType()

Returns a short string describing the type of plot.

Specified by:

getPlotType in class Plot

Returns:

The plot type.

getLegendItemShape

public Shape getLegendItemShape()

Returns the shape used for legend items.

Returns:

The shape (never null).

See Also:

• setLegendItemShape(Shape)

setLegendItemShape

public void setLegendItemShape(Shape shape)

Sets the shape used for legend items and sends a PlotChangeEvent to all registered listeners.

Parameters:

shape - the shape (null not permitted).

See Also:

• getLegendItemShape()

draw

public void draw(Graphics2D g2,
 Rectangle2D area,
 Point2D anchor,
 PlotState parentState,

Specified by:

draw in class 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.

getLegendItems

public LegendItemCollection getLegendItems()

Returns a collection of legend items for the pie chart.

Specified by:

getLegendItems in interface LegendItemSource

Overrides:

getLegendItems in class Plot

Returns:

The legend items.

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 class Plot

Parameters:

obj - the object (null permitted).

Returns:

true if this plot is equal to obj, and false otherwise.

clone

public Object clone()
             throws CloneNotSupportedException
