JFreechartフィリングセクタシリーズ

Question

極座標プロットの各領域に塗りつぶしシリーズを作成しようとしています。しかし、色は右に記入されていません。ここで私は何を得るのイメージは次のとおりです。http://i1122.photobucket.com/albums/l539/jpo2/polar-1.gif ここで私は与えられたセクションをループしていたコードがあり、次のようにされています。これはJFreechart Loop through polar chart sectors での@ trashgodのdrawメソッドの変更である

if (i < 8) { 
    for(int r = 0; r< 20; r+=(NumberAxis) plot.getAxis()).getTickUnit().getSize()){ 
    for(int theta = 0; theta <= 180; theta+=30){ 
    XYSeries series = new XYSeries(i + "π/8 " + "< θ < 2π+" + i + "π/8"); 
     for (int e = theta; e < theta+30; e++) { 
      series.add(90-e-i*45, r); 
      series.add(90-e-i*45, r- ((NumberAxis) plot.getAxis()).getTickUnit().getSize()); 
      } 
     result.addSeries(series); 
     setFilled(result); 
     i++; 
     } 
    } 
    } 
private void setFilled(XYDataset dataset) { 
    for (int i = 0; i < dataset.getSeriesCount(); i++) { 
     renderers.setSeriesFilled(i, true); 
     } 
    } 

助けてください。

は、ここで任意の変換なしで、用途PolarPlot直接簡易版です。実験するのは簡単かもしれません。
