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: https://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。

// 在要显示统计图的页面代码直接调用，方法类似如下：
//
// ShowData show=new ShowData();
// show.Title ="2008年各月消费情况统计";
// show.XTitle ="月份";
// show.YTitle ="金额(万元)";
// show.PicHight =300;

// show.SeriesName ="具体详情";
// show.PhaysicalImagePath ="ChartImages";
// show.DataSource =this.GetDataSource();
// show.CreateColumn(this.Chart1);
