Constructor Detail

### 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 Detail

### getDataset

    public CategoryDataset getDataset()

  Returns the dataset used by the plot.

  Returns:
    The dataset (possibly `null`).

### setDataset

    public void setDataset(CategoryDataset dataset)

  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).

    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 org.jfree.util.TableOrder getDataExtractOrder()

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

  Returns:
    The data extract order (never `null`).

### setDataExtractOrder

    public void setDataExtractOrder(org.jfree.util.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
