asp实现k线图(在线)(1) 可以考虑使用MSCHART，但是缺点是显示不太好看，不很专业，同时，如果客户端没有装的话就比较麻烦，因为显示不出来，所以一般的网站都采用生成图片的方式。下面给出MSCHART的一些东西，可以自己考虑着使用，我没有使用过其他的控件，所以不能给你满意的答复。另外附给你一个网址，www.tjinfo.com,里面有个调查题，使用了MSCHART，但是没有用折线，这个你可以自己定义的，CSDN的调查也使用了MSCHART。

看看我的这篇总结，你会受益匪浅！
关于Mschart的说明文档
MsChart是微软制作的功能强大的图表工具，用它可以很方便的建立各种图表。制作各种3维2维的直方图，折线图。结合前一段时间我对Mschart组件的认识，谈谈Mschart组件的使用方法。
1、 Chart Activex控件：
In the HTML page, insert an <OBJECT> tag for the License Manager object before any other <OBJECT> tags. The License Manager is an ActiveX control that is installed with Internet EXPlorer.
NOTE: This CLASSID, "5220cb21-c88d-11cf-b347-00aa00a28331", is for the License Manager and not for your ActiveX controls. You must use the same CLASSID every time you refer to the LPK file. In addition, you should keep the Name property of the <PARAM> tag as "LPKPath", and set the Value property for the <PARAM> tag of the License Manager object to the LPK file name and path. This path may be a relative path but must not refer to a UNC share or a URL on another domain.
Because you can only have one LPK file for each HTML page, make sure that you include all of the licensed ActiveX Controls for the page when you generate your LPK file. For example:
<object CLASSID="clsid:5220cb21-c88d-11cf-b347-00aa00a28331"
id="Microsoft_Licensed_Class_Manager_1_0">
<param NAME="LPKPath" VALUE="mschart.lpk">
</object>
Insert the <OBJECT> tag for your licensed control afterward. For example, an HTML page that displays the Microsoft Masked Edit control looks like this.
Here I downloaded the file mschart.cab from Microsoft's website. It has been digitally signed.
