100分紧急求救----JFreeChart的使用

有jchart要么？我可以给你了代码的例子，和文档

网上大多是web开发方面的例子，所以来请大牛来了

这个类够你用了，折线图，饼状图和柱状图都有了

请问你这个是基于JFreeChart的那个版本的？

求
jfreechart-1.0.13
应该怎么使用? 导入哪几个类？

求
jfreechart-1.0.13
应该怎么使用? 导入哪几个类？到CSDN去下一个看看，有的。看看楼上的文章，就差不多了，

网上没有对应的jar包么？csdn下载里也应该有。其他的就是找官方的实例了。

这里有详细的介绍，应该对你有用：http://www.blogjava.net/chunkyo/archive/2007/01/13/jfreechat.html
