Question

  final PiePlot plot = (PiePlot) chart.getPlot();
  for (int i = 0; i < 2; i++) {
    plot.setSectionPaint(i, color[i]);
    plot.setSectionPaint(plot.getSectionKey(i), color[i]);
  }

I try to set some other color to the section of a PieChart.

setSectionPaint(int, Color) method is deprecated

setSectionPaint(Comparable, Color) method : I cannot get a Comparable object because plot.getSectionKey(int index ) is protected.

Is there a solution so I can change color of sections without error/warn message ?
Or how to retrieve the comparable object ?

Answer 1

You need to supply the correct Comparable key from your data set to invoke the desired implementation of setSectionPaint(). For example, in org.jfree.chart.demo.PieChartDemo1, the following would set section One to Color.black.

plot.setSectionPaint("One", Color.black);
