最主要的是设置font

柱状图(CategoryPlot):
    CategoryPlot plot=chart.getCategoryPlot();//获取图表区域对象
   CategoryAxis domainAxis=plot.getDomainAxis();
    //水平底部列表
    domainAxis.setLabelFont(new Font("黑体",Font.BOLD,14));
    //水平底部标题
    domainAxis.setTickLabelFont(new Font("宋体",Font.BOLD,12));
    //垂直标题
    ValueAxis rangeAxis=plot.getRangeAxis();//获取柱状
    rangeAxis.setLabelFont(new Font("黑体",Font.BOLD,15));
     chart.getLegend().setItemFont(new Font("黑体", Font.BOLD, 15));
饼图(PiePlot):
     JFreeChart chart = ChartFactory.createPieChart3D("IT行业职业分布图", dataset, true, false, false);
    chart.getTitle().setFont(new Font("黑体",Font.BOLD,20));//设置标题字体
    PiePlot piePlot= (PiePlot) chart.getPlot();//获取图表区域对象
    piePlot.setLabelFont(new Font("黑体",Font.BOLD,10));
    chart.getLegend().setItemFont(new Font("黑体",Font.BOLD,10));
时序图(TimeSeries)  
   XYPlot plot = (XYPlot) chart.getPlot();
    //纵轴字体
    plot.getRangeAxis().setLabelFont(new Font("宋体", Font.BOLD, 15));
    //横轴框里的标题字体
    chart.getLegend().setItemFont(new Font("宋体", Font.ITALIC, 15));
    //横轴列表字体
    plot.getDomainAxis().setTickLabelFont(new Font("新宋体", 1, 15));
    //横轴小标题字体
    plot.getDomainAxis().setLabelFont(new Font("新宋体", 1, 12));
折线图
chart.getTitle().setFont(new Font("宋体", Font.BOLD, 15));
   chart.getLegend().setItemFont(new Font("黑体", Font.BOLD, 15));
   CategoryAxis domainAxis = plot.getDomainAxis();   
   /*------设置X轴坐标上的文字-----------*/ 
   domainAxis.setTickLabelFont(new Font("黑体", Font.PLAIN, 11));   
   /*------设置X轴的标题文字------------*/ 
   domainAxis.setLabelFont(new Font("宋体", Font.PLAIN, 12));   
   NumberAxis numberaxis = (NumberAxis) plot.getRangeAxis();   
   /*------设置Y轴坐标上的文字-----------*/ 
   numberaxis.setTickLabelFont(new Font("黑体", Font.PLAIN, 12));   
    
   /*------设置Y轴的标题文字------------*/ 
   numberaxis.setLabelFont(new Font("黑体", Font.PLAIN, 12))
