一个功能强大超级好用的图表组件Dundas Chart

最近因为项目需要，需要为客户的统计数据生成图表，包括柱状图和饼图。我找来了Dundas Software的Dundas Chart，大家可以上它的网站http://www.dundas.com/查看最新版本的信息以及下载该软件它确实是一个功能强大的组件，而且用户友好性方面很值得国产软件学习。

闲话少说，进入该软件的使用。先安装该软件，安装后它包括两个非常有用的功能，一个是做的非常类似msdn的帮助文档，相信对.net程序员非常友好，就当是msdn用吧。另外一个是它的sample，这是一个完整的.net解决方案，你可以在IIS里面配置个网站来访问它。接着你就可以开始通过sample来了解和学习Dundas Chart的强大功能了。

下面给个我学习中生成的图片。
