jfreechart解决中文乱码问题
出现乱码的运行效果
?
原始程序如下

??? String s6 = "D网站";
??? String s7 = "E网站";
??? DefaultCategoryDataset defaultcategorydataset = new DefaultCategoryDataset();
??? defaultcategorydataset.addValue(1.0D, s, s3);
??? defaultcategorydataset.addValue(4D, s, s4);

? private static JFreeChart createChart(CategoryDataset categorydataset) {
??? JFreeChart jfreechart = ChartFactory.createBarChart("Bar Chart Demo 1", "网站", "数值",
??????? categorydataset, PlotOrientation.VERTICAL, true, true, false);
??? CategoryPlot categoryplot = (CategoryPlot) jfreechart.getPlot();
??? categoryplot.setDomainGridlinesVisible(true);
??? categoryplot.setRangeCrosshairVisible(true);
??? categoryplot.setRangeCrosshairPaint(Color.blue);
??? NumberAxis numberaxis = (NumberAxis) categoryplot.getRangeAxis();
??? numberaxis.setStandardTickUnits(NumberAxis.createIntegerTickUnits());
??? BarRenderer barrenderer = (BarRenderer) categoryplot.getRenderer();
??? barrenderer.setBaseItemLabelFont(new Font("宋体", Font.PLAIN, 12));
??? barrenderer.setSeriesItemLabelFont(1, new Font("宋体", Font.PLAIN, 12));
???
??? barrenderer.setDrawBarOutline(false);
??? GradientPaint gradientpaint = new GradientPaint(0.0F, 0.0F, Color.blue, 0.0F, 0.0F, new Color(
??????? 0, 0, 64));
??? GradientPaint gradientpaint1 = new GradientPaint(0.0F, 0.0F, Color.green, 0.0F, 0.0F,
??????? new Color(0, 64, 0));
??? GradientPaint gradientpaint2 = new GradientPaint(0.0F, 0.0F, Color.red, 0.0F, 0.0F, new Color(
??????? 64, 0, 0));
??? barrenderer.setSeriesPaint(0, gradientpaint);
??? barrenderer.setSeriesPaint(1, gradientpaint1);
??? barrenderer.setSeriesPaint(2, gradientpaint2);
??? barrenderer.setLegendItemToolTipGenerator(new StandardCategorySeriesLabelGenerator(
??????? "Tooltip: {0}"));
??? CategoryAxis categoryaxis = categoryplot.getDomainAxis();
??? categoryaxis.setCategoryLabelPositions(CategoryLabelPositions
??????? .createUpRotationLabelPositions(0.52359877559829882D));
??? return jfreechart;
? }
? public static JPanel createDemoPanel() {
??? JFreeChart jfreechart = createChart(createDataset());
??? return new ChartPanel(jfreechart);
? }
? public static void main(String args[]) {
??? BarChartDemo1 barchartdemo1 = new BarChartDemo1("黑体JFreeChart: BarChartDemo1.java");
??? barchartdemo1.pack();
??? RefineryUtilities.centerFrameOnScreen(barchartdemo1);
??? barchartdemo1.setVisible(true);
? }
}
增加如下的代码，解决汉字乱码问题
??? CategoryAxis domainAxis = categoryplot.getDomainAxis();
??? /*------设置X轴坐标上的文字-----------*/
??? domainAxis.setTickLabelFont(new Font("sans-serif", Font.PLAIN, 11));
??? /*------设置X轴的标题文字------------*/
??? domainAxis.setLabelFont(new Font("宋体", Font.PLAIN, 12));
??? /*------设置Y轴坐标上的文字-----------*/
??? numberaxis.setTickLabelFont(new Font("sans-serif", Font.PLAIN, 12));
???
??? /*------设置Y轴的标题文字------------*/
??? numberaxis.setLabelFont(new Font("黑体", Font.PLAIN, 12));
??? /*------这句代码解决了底部汉字乱码的问题-----------*/
??? jfreechart.getLegend().setItemFont(new Font("宋体", Font.PLAIN, 12));
运行效果如下
