如何把一個Chart3D在一個JPanel

Question

我工作的一個Java Swing應用程序，我發現把一個Chart3D在一個JPanel或框架的問題，這是我的代碼

private void initChart(){ 

    CategoryDataset3D dataset = createDataset(); 
     Chart3D chart = Chart3DFactory.createStackedBarChart(
       "Personnel répartition,", 
       "repartition pour 480 personnel ", 
       dataset, null, 
       "Class", "Personnel"); 
    ImageIcon icon = new ImageIcon("/Users/dgilbert/Desktop/iStock_000003105870Small.jpg"); 
     RectanglePainter background = new StandardRectanglePainter(Color.WHITE, 
       icon.getImage(), new Fit2D(TitleAnchor.CENTER, 
       Scale2D.SCALE_BOTH)); 
      chart.setChartBoxColor(new Color(255, 255, 255, 155)); 
       CategoryPlot3D plot = (CategoryPlot3D) chart.getPlot(); 
//  StackedBarRenderer3D renderer = (StackedBarRenderer3D) plot.getRenderer(); 
//  renderer.setColorSource(new StandardCategoryColorSource(new Color[] { new Color(50, 200, 50),new Color(200, 50, 50) })); 
      final ChartPanel chartPanel = new ChartPanel(chart); 
      Frame frame = new ChartFrame("tokens pert time", chart); 
      frame.setSize(550,450); 

問題： 最終ChartPanel chartPanel =新ChartPanel（圖表）; Frame frame = new ChartFrame（「tokens pert time」，chart）;在這兩行，它出現一個錯誤「Chart3D cannor被轉換到j freeChart」 -

正如你可能在使用orson-charts，你可能會尋找Chart3DPanel，如圖Getting Started。

Chart3DPanel chartPanel = new Chart3DPanel(chart);
