Ready环境：JFreeChart 1.0.1、iText1.3 JFreeChart1.0.1中的Plot接口没有提供SetValueLabelFont的方法，无法直接设置label的字体！不过还好试了一下午总算弄出来了，具体代码如下： 

PdfWriter writer; writer = PdfWriter.getInstance(document, new FileOutputStream( filename)); document.open(); PdfContentByte cb = writer.getDirectContent(); PdfTemplate tp = cb.createTemplate(width, height); // 关键是使用AsianFontMapper替代DefaultFontMapper AsianFontMapper mapper = new AsianFontMapper("STSong-Light","UniGB-UCS2-H"); Graphics2D g2d = tp.createGraphics(width, height, mapper); Rectangle2D r2d = new Rectangle2D.Double(0, 0, width, height); chart.draw(g2d, r2d); g2d.dispose(); cb.addTemplate(tp, 0, 0);

记住别忘了添加iTextAisan.jar不然会报如下错误：下载地址：iTextAsian.jar下载（32&64位）
