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)
Sets the dataset used by the plot and sends aPlotChangeEvent
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 ofPiePlot
.- Parameters:
pieChart
- the pie chart (null
not permitted).- See Also:
getPieChart()
