.net使用DotNetCharting控件生成报表统计图总结

最近在做项目时要对数据进行统计分析，所以必须生成一些报表统计图(如柱形图、饼图、曲线图等)，网上强烈推荐了使用DotNetCharting控件来实现，于是自己对DotNetCharting控件进行了简单的学习，下面先简单介绍一下DotNetCharting控件及其使用。

    DotNetCharting是一个非常棒的.NET图表控件，对中文支持非常好，而且操作方便，开发快速，既有for webform 也有for winform的，而且.net1.1和2.0都有支持。它的官方地址是http://www.dotnetcharting.com/

    本站也提供了DotNetCharting破解版本下载: http://files.cnblogs.com/dreamof/dotnetcharting.rar

    强烈推荐一下DotNetCharting的demo地址：
    这个是所有的 DEMO 演示  http://www.dotnetcharting.com/demo.aspx
    这个是 Online Documentation http://www.dotnetcharting.com/documentation/v4_4/webframe.html 里面会有详细的说明和用法。

    DotNetCharting的简单使用方法：
    1.把\bin\dotnetCHARTING.dll添加到工具箱，并且添加引用;

    2.把控件拖到你的网页上，然后添加引用using dotnetCHARTING;就可以用了;

    3.接下来是自己写的对DotNetCharting操作的封装类，以便于在程序里调用。
