解决JFreeChart中文乱码问题

JFreeChart chart = ChartFactory.createBarChart3D("管网损耗",// 图表标题
"时间（" + x_name + "）",// 目录轴的显示标签
"单位时间内损耗的能量", // 数值轴的显示标签
categoryDataset, // 数据集
PlotOrientation.VERTICAL,// 图表方向：水平、垂直
true, // 是否显示图例(对于简单的柱状图必须是false)
true,// 是否生成工具
false// 是否生成URL链接
);

// 副标题
TextTitle subtitle = new TextTitle(meterPosition + "表计管网损耗",
new Font("黑体", Font.BOLD, 12));
chart.addSubtitle(subtitle);
chart.setTitle(chart.getTitle()); // 标题

CategoryPlot plot = chart.getCategoryPlot();// 获得图表区域对象
// 设置图表的纵轴和横轴org.jfree.chart.axis.CategoryAxis
CategoryAxis domainAxis = plot.getDomainAxis();
NumberAxis numberaxis = (NumberAxis) plot.getRangeAxis();

// 解决中文乱码问题
TextTitle textTitle = chart.getTitle();
textTitle.setFont(new Font("黑体", Font.PLAIN, 20));
domainAxis.setTickLabelFont(new Font("sans-serif", Font.PLAIN, 11));
domainAxis.setLabelFont(new Font("宋体", Font.PLAIN, 20));
numberaxis.setTickLabelFont(new Font("sans-serif", Font.PLAIN, 12));
numberaxis.setLabelFont(new Font("黑体", Font.PLAIN, 16));
chart.getLegend().setItemFont(new Font("宋体", Font.PLAIN, 12));
