最主要的是設置font

柱狀圖(CategoryPlot):
    CategoryPlot plot=chart.getCategoryPlot();//獲取圖表區域對象
   CategoryAxis domainAxis=plot.getDomainAxis();
    //水平底部列表
    domainAxis.setLabelFont(new Font("黑體",Font.BOLD,14));
    //水平底部標題
    domainAxis.setTickLabelFont(new Font("宋體",Font.BOLD,12));
    //垂直標題
    ValueAxis rangeAxis=plot.getRangeAxis();//獲取柱狀
    rangeAxis.setLabelFont(new Font("黑體",Font.BOLD,15));
     chart.getLegend().setItemFont(new Font("黑體", Font.BOLD, 15));
餅圖(PiePlot):
     JFreeChart chart = ChartFactory.createPieChart3D("IT行業職業分布圖", dataset, true, false, false);
    chart.getTitle().setFont(new Font("黑體",Font.BOLD,20));//設置標題字體
    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.BOLD,10));
時序圖(TimeSeries)  
   XYPlot plot = (XYPlot) chart.getPlot();
    //縱軸字體
    plot.getRangeAxis().setLabelFont(new Font("宋體", Font.BOLD, 15));
    //橫軸框里的標題字體
    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));
折線圖
chart.getTitle().setFont(new Font("宋體", Font.BOLD, 15));
   chart.getLegend().setItemFont(new Font("黑體", Font.BOLD, 15));
   CategoryAxis domainAxis = plot.getDomainAxis();   
   /*------設置X軸坐標上的文字-----------*/ 
   domainAxis.setTickLabelFont(new Font("黑體", Font.PLAIN, 11));   
   /*------設置X軸的標題文字------------*/ 
   domainAxis.setLabelFont(new Font("宋體", Font.PLAIN, 12));   
   NumberAxis numberaxis = (NumberAxis) plot.getRangeAxis();   
   /*------設置Y軸坐標上的文字-----------*/ 
   numberaxis.setTickLabelFont(new Font("黑體", Font.PLAIN, 12));   
    
   /*------設置Y軸的標題文字------------*/ 
   numberaxis.setLabelFont(new Font("黑體", Font.PLAIN, 12))
