JFreeChart 中文乱码解决(不用添加iTextAsian.jar)
JFreeChart 中文乱码主要是缺少字体,可将其字体设置为系统存在的字体，乱码即可解决:
public static java.awt.Font getFont(){
java.awt.Font font;
try {
File fontFile = ResourceUtils.getFile("classpath:font/simsun.ttc");//字体文件要放在class path的font文件夹下
GraphicsEnvironment gEnv = GraphicsEnvironment.getLocalGraphicsEnvironment();
String[] evnfonts = gEnv.getAvailableFontFamilyNames();
List<String> list = Arrays.asList(evnfonts);
if (!list.contains("宋体")) {//系统没有安装宋体，用字体文件创建一个
font = java.awt.Font.createFont(java.awt.Font.TRUETYPE_FONT, fontFile);
} else {
font = new java.awt.Font("宋体", java.awt.Font.PLAIN, 12);//读取系统字体
}
return font;
} catch (FileNotFoundException e) {
log.error("The font file is not exist! Please add the simsun font file to 'classpath:font/simsun.ttc'.");
} catch (Exception e) {
log.error("Error occured when creating simsun font.");
}
return null;
}
设置JFreeChart 字体:
public static JFreeChart createBarChart3D(DefaultCategoryDataset dataset,String title, String xAxisLabel, String yAxisLabel) {
JFreeChart chart = ChartFactory.createBarChart3D(title, xAxisLabel, yAxisLabel, dataset, PlotOrientation.VERTICAL, false,
false, false);
CategoryPlot plot = chart.getCategoryPlot();
chart.setBackgroundPaint(Color.WHITE);
BarRenderer3D renderer = new BarRenderer3D();
renderer.setBaseOutlinePaint(Color.BLACK);
renderer.setMaximumBarWidth(0.1);
renderer.setSeriesPaint(0, new Color(20, 180, 20));
renderer.setItemMargin(0.1);
renderer.setBaseItemLabelGenerator(new StandardCategoryItemLabelGenerator());
renderer.setItemLabelPaint(Color.BLACK);
renderer.setItemLabelsVisible(true);
renderer.setBaseItemLabelsVisible(true);
renderer.setBasePositiveItemLabelPosition(new ItemLabelPosition(ItemLabelAnchor.OUTSIDE12, TextAnchor.BASELINE_LEFT));
plot.setRenderer(renderer);
plot.setForegroundAlpha(0.8f);
Font font = FontUtils.getFont();
if(font != null){
plot.getDomainAxis().setLabelFont(font);
plot.getDomainAxis().setTickLabelFont(font);
plot.getRangeAxis().setLabelFont(font);
plot.getRangeAxis().setTickLabelFont(font);
Font titleFont = font.deriveFont(Font.BOLD,22);
chart.getTitle().setFont(titleFont);
}
return chart;
}
