sein in JFreeChart möglich, versuchen Sie so etwas wie diese.

RingPlot plot = new RingPlot(dataset); 
StringBuffer chartFileName = new StringBuffer(Integer.toString(generatedCharts)).append(Long.toString(System.currentTimeMillis())).append(".png"); 

JFreeChart chart = new JFreeChart("", JFreeChart.DEFAULT_TITLE_FONT, plot, true); 
chart.setBackgroundPaint(new GradientPaint(new Point(0, 0), new Color(20, 20, 20), new Point(400, 200), Color.DARK_GRAY)); 

TextTitle t = chart.getTitle(); 
t.setHorizontalAlignment(org.jfree.ui.HorizontalAlignment.LEFT); 
t.setPaint(new Color(240, 240, 240)); 
t.setFont(new Font("Arial", Font.BOLD, 26)); 

plot.setBackgroundPaint(null); 
plot.setOutlineVisible(false); 
plot.setLabelGenerator(null); 
plot.setSectionDepth(0.35); 
plot.setSectionOutlinesVisible(false); 
plot.setSimpleLabels(true); 
plot.setShadowPaint(null); 
plot.setOuterSeparatorExtension(0); 
plot.setInnerSeparatorExtension(0); 
plot.setLabelGenerator(new StandardPieSectionLabelGenerator("{1}",new DecimalFormat("#,##0"), new DecimalFormat("0.000%"))); 
plot.setLabelBackgroundPaint(null); 
plot.setLabelOutlinePaint(null); 

Font font=new Font("",0,16); 
plot.setLabelFont(font); 

chart.getLegend().setFrame(BlockBorder.NONE); 
chart.getLegend().setPosition(RectangleEdge.BOTTOM); 
chart.setBackgroundPaint(java.awt.Color.white); 
chart.setPadding(new RectangleInsets(4, 8, 2, 2)); 

Out Put wird
