我如何在asp.net应用程序的应用程序中添加图形
问题描述：
我想使用c#在asp.net中创建折线图，因此在x轴上将显示时间，在y轴上将显示货币.出价和要价两个值将在图中的红色和蓝色两行显示.该图从数据库中获取值，并每秒更新一次，因此该图应该是连续的.

最明显的方法之一是将Microsoft Chart Control用于ASP.NET:
http://www.microsoft.com/en-us/download/details.aspx? id = 14422 [^ ]，
http://www.asp.net/community/control-gallery/Item.aspx? i = 3110 [ ^ ]，

One of the most apparent ways is using Microsoft Chart Control for ASP.NET:
