更改 jfreechart 的域轴标签和范围轴标签的字体大小

Question

我的目标是增加“Revenue ($)”和“Years”的大小。但是我不知道怎么做。我可以增加“Apples, Durians,Oranges”和“2012, 2013”​​。

以下是我的代码。

    JFreeChart chart = ChartFactory.createBarChart3D("", // chart title
                "Years", // domain axis label
                "Revenue ($)", // range axis label
                dataset, // data
                PlotOrientation.VERTICAL, // orientation
                false, // include legend
                false, // tooltips
                false);

CategoryPlot plot = chart.getCategoryPlot();
        CategoryAxis axis = plot.getDomainAxis();

        CategoryPlot p = chart.getCategoryPlot(); 
         ValueAxis axis2 = p.getRangeAxis();

        Font font = new Font("Dialog", Font.PLAIN, 25);
        axis.setTickLabelFont(font);
        Font font2 = new Font("Dialog", Font.PLAIN, 15);
        axis2.setTickLabelFont(font2);

        LegendTitle legend = new LegendTitle(plot.getRenderer());

        Font font3 = new Font("Dialog", Font.PLAIN, 20); 
        legend.setItemFont(font3); 
        legend.setPosition(RectangleEdge.BOTTOM); 
        chart.addLegend(legend); 

Answer 1

使用

CategoryPlot plot = chart.getCategoryPlot();
Font font3 = new Font("Dialog", Font.PLAIN, 25); 
plot.getDomainAxis().setLabelFont(font3);
plot.getRangeAxis().setLabelFont(font3);
