Title

TextTitle textTitle = freeChart.getTitle();
textTitle.setFont(new Font("宋體",Font.BOLD,20));

對於使用CategoryPlot的圖表(如柱狀圖):

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

對於使用PiePlot的圖標(如餅狀圖)：

PiePlot plot = (PiePlot)freeChart.getPlot();
plot.setLabelFont(new Font("宋體",Font.BOLD,15));
