getPieChart

public JFreeChart getPieChart()

Returns the pie chart that is used to draw the individual pie plots.

Returns:

the pie chart.

setPieChart

public void setPieChart(JFreeChart pieChart)

Sets the chart that is used to draw the individual pie plots.

Parameters:

pieChart - the pie chart.

getDataExtractOrder

public org.jfree.util.TableOrder getDataExtractOrder()
