Schreiben J Kostenloses Diagramm mit chinesischen Etiketten Zum pdf

Question

Ich versuche, ein JFree-Diagramm mit chinesischen Bezeichnungen zu schreiben. Zu PDf, kann ich das Diagramm in pdf ohne lables sehen. Aber ich brauche ein Diagramm mit Etiketten.

Unten ist das Code-Snippet. Kann mir bitte jemand helfen?

public static void main(String[] args) throws Exception { 


       writeChartToPDF(generatePieChart(), 500, 400, "2.pdf"); 


    } 

public JFreeChart generatePieChart() throws SQLException { 
     java.awt.Font font = new java.awt.Font("c:\\fonts\\SimHei Regular.TTF", java.awt.Font.HANGING_BASELINE,8); 
     JFreeChart localJFreeChart = ChartFactory.createRingChart("", dataSet, true, false, false); 
     RingPlot localRingPlot = (RingPlot)localJFreeChart.getPlot(); 
     localRingPlot.setLabelFont(font); 
     localRingPlot.setNoDataMessage("No data available"); 
     localRingPlot.setNoDataMessageFont(font); 
     localRingPlot.setNoDataMessagePaint(Color.darkGray); 
     localRingPlot.setSectionDepth(0.75D); 
     localRingPlot.setCircular(true); 
     localRingPlot.setLabelGap(0.02D); 
     localRingPlot.setSeparatorsVisible(true); 
     localRingPlot.setSeparatorPaint(Color.white); 
     localRingPlot.setShadowPaint(Color.white); 
     localRingPlot.setOutlineVisible(false); 
     localRingPlot.setBackgroundPaint(Color.white); 
     localRingPlot.setLabelLinkStyle(PieLabelLinkStyle.STANDARD); 

     localRingPlot.setLabelBackgroundPaint(Color.WHITE); 
     localRingPlot.setLabelOutlinePaint(Color.WHITE); 
     localRingPlot.setLabelShadowPaint(null); 

     colorRingPlot(localRingPlot, dataSet); 
     localJFreeChart.removeLegend(); 

     localRingPlot.setBaseSectionOutlinePaint(Color.white); 
     localJFreeChart.setBackgroundPaint(Color.white); 
     localJFreeChart.setBorderVisible(false); 
     return localJFreeChart; 
    } 

private static void colorRingPlot(RingPlot plot, DefaultPieDataset dataset) { 

     Double dataVal ; 

     for (int i = 0; i < dataset.getItemCount(); i++) { 
      dataVal= (Double) dataset.getValue(i); 
      if(dataVal >= 20){ 
       plot.setSectionPaint(dataset.getKey(i), colorRange[0]); 
      }else if(dataVal >= 10 && dataVal < 20){ 
       plot.setSectionPaint(dataset.getKey(i), colorRange[1]); 
      }else if((dataVal > 0) && (dataVal < 10)){ 
       plot.setSectionPaint(dataset.getKey(i), colorRange[2]); 
      }   
     } 
    } 


private static final Color[] colorRange = { new Color(111,191,103), new Color(169,217,164), new Color(210,235,205) }; 



private PieDataset createDataset() { 
     DefaultPieDataset result = new DefaultPieDataset(); 
     result.setValue("短期资 (68.20%)", 0); 
     result.setValue("股 (1.87%)", 2); 
     result.setValue("同基金s (3.95%)", 3); 
     result.setValue("另投资 (8.19%))", 5); 
     result.setValue("债 (7.96%)", 1); 
     result.setValue("其投资 (2.81%))", 6); 
     result.setValue("组合资 (7.02%)", 4); 
     return result; 
     } 




public static void writeChartToPDF(JFreeChart chart, int width, int height, String fileName) { 
     PdfWriter writer = null; 
     BaseFont bfA = null ; 

     Document document = new Document(); 

     try { 
      bfA = BaseFont.createFont("c:\\S24_Statements\\HK\\rundir\\fonts\\SimHei Regular.TTF", BaseFont.IDENTITY_H, 
       BaseFont.EMBEDDED); 
      writer = PdfWriter.getInstance(document, new FileOutputStream(
        fileName)); 
      document.open(); 
      PdfContentByte contentByte = writer.getDirectContent(); 
      FontFactory.getFont("GulimChe", BaseFont.IDENTITY_H, true, Font.BOLD, 
        14); 

      DefaultFontMapper dfm=new DefaultFontMapper(); 
      dfm.pdfToAwt(bfA, 8); 
      PdfTemplate template = contentByte.createTemplate(width, height); 
      Graphics2D graphics2d = template.createGraphics(width, height, 
        dfm); 
      Rectangle2D rectangle2d = new Rectangle2D.Double(0, 0, width, 
        height); 

      chart.draw(graphics2d, rectangle2d); 

      graphics2d.dispose(); 
      contentByte.addTemplate(template, 0, 0); 

     } catch (Exception e) { 
      e.printStackTrace(); 
     } 
     document.close(); 
    }

FontMapper arialuni = new FontMapper() { 
      public BaseFont awtToPdf(Font font) { 
       try { 
        return BaseFont.createFont(
          "c:/windows/fonts/arialuni.ttf", 
          BaseFont.IDENTITY_H, BaseFont.EMBEDDED); 
       } catch (DocumentException e) { 
        e.printStackTrace(); 
       } catch (IOException e) { 
        e.printStackTrace(); 
       } 
       return null; 
      } 

      public Font pdfToAwt(BaseFont font, int size) { 
       return null; 
      } 

     };
