C#.net使用DotNetCharting控件生成报表统计图

1、C#.net使用DotNetCharting控件生成报表统计图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

3、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。ShowData.csusing System;using System.Data;using System.Text;using dotnetCHARTING;namespace FLX.ComplexQuery    /*/ <summary>        / 彭建军    /
