JFreechart亂碼的解決辦法

對於餅圖(PiePlot):

chart.getTitle().setFont(new Font("黑體", Font.PLAIN, 20));//標題
  PiePlot piePlot = (PiePlot) chart.getPlot();// 獲取圖表區域對象
  piePlot.setLabelFont(new Font("黑體", Font.BOLD, 10));

  chart.getLegend().setItemFont(new Font("黑體", Font.PLAIN, 12));//圖釋

 

柱狀圖(CategoryPlot):

CategoryPlot plot = (CategoryPlot)freeChart.getPlot();  
CategoryAxis domainAxis = plot.getDomainAxis();//(柱狀圖的x軸)  
domainAxis.setTickLabelFont(new Font("宋體",Font.BOLD,20));//設置x軸座標上的字體  
domainAxis.setLabelFont(new Font("宋體",Font.BOLD,20));//設置x軸上的標題的字體    
ValueAxis valueAxis = plot.getRangeAxis();//(柱狀圖的y軸)  
valueAxis.setTickLabelFont(new Font("宋體",Font.BOLD,20));//設置y軸座標上的字體  
valueAxis.setLabelFont(new Font("宋體",Font.BOLD,20));//設置y軸座標上的標題的字體 

chart.getLegend().setItemFont(new Font("黑體", Font.PLAIN, 12));//圖釋

時序圖(TimeSeries)    XYPlot :

   XYPlot plot = (XYPlot) chart.getPlot();
    //縱軸字體
    plot.getRangeAxis().setLabelFont(new Font("宋體", Font.BOLD, 15));
    //橫軸框裏的標題字體
    chart.getLegend().setItemFont(new Font("宋體", Font.ITALIC, 15));
    //橫軸列表字體
    plot.getDomainAxis().setTickLabelFont(new Font("新宋體", 1, 15));
    //橫軸小標題字體
    plot.getDomainAxis().setLabelFont(new Font("新宋體", 1, 12));
