Change font-size of domain axis label and range axis label for jfreechart

Question

My goal is to increase the size of "Revenue ($) " and "Years". But I do not know how. I am able to increase the "Apples, Durians,Oranges" and "2012, 2013".

Below are my codes.

    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

Use

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