功能强大的图表控件（chart 控件）包含于：Microsoft Chart Controls for Microsoft .NET Framework 4.5中
一、需在工程中添加需要的引用.DLL文件
1. 在WinForm应用程序中要想使用该图表控件，需引用如下DLL:
System.Windows.Forms.DataVisualization.Design.dll
System.Windows.Forms.DataVisualization.dll
System.Windows.Forms.DataVisualization.xml
2. 在Web应用程序中要想使用该图表控件，需引用如下DLL:
System.Web.DataVisualization.dll
System.Web.DataVisualization.Design.dll
System.Web.DataVisualization.xml
文件一般保存于 C:\Windows\Microsoft.NET\Framework64\v4.0.30319目录下面。
为了画柱状图，添加以下程序
