JFreeChart标签宽度

Question

我是JFreeChart的新手。

附上我的图表。如您所见，标签被截断。如何指定标签的宽度以避免截断（我有足够的空间来容纳它们）？

我目前的代码如下：

   DefaultCategoryDataset dataset = new DefaultCategoryDataset();

    dataset.setValue(24, "Major", "Mathematics");
    dataset.setValue(20, "Major", "Philosophy");
    dataset.setValue(18, "Major", "Chemical Engineering");
    dataset.setValue(15, "Major", "Sociology");
    dataset.setValue(14, "Major", "Stuff");
    dataset.setValue(13, "Major", "A Program");
    dataset.setValue(13, "Major", "Bleg");

    JFreeChart chart = ChartFactory.createBarChart(" ", "Major", "Score", dataset, PlotOrientation.HORIZONTAL,
            false, true, false);
    CategoryPlot plot = chart.getCategoryPlot();

    Font font1 = new Font("Dialog", Font.PLAIN, 25);
    Font font2 = new Font("Dialog", Font.PLAIN, 15);
    Font font3 = new Font("Dialog", Font.PLAIN, 25);

    plot.getDomainAxis().setLabelFont(font3);
    plot.getRangeAxis().setLabelFont(font3);

    CategoryAxis axisDomain = plot.getDomainAxis();
    ValueAxis axisRange = plot.getRangeAxis();

    axisDomain.setTickLabelFont(font1);

    axisRange.setTickLabelFont(font2);
    chart.setAntiAlias(true);

在建议的here方法中，以下示例会覆盖if ( (x-c0|c0-x) & (x-c1|c1-x) & ... & (x-cn|cn-x) & 0x80) { // x is not equal to any ci 。
