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。

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.
<OBJECT classid="clsid:3A2B370C-BA0A-11D1-B137-0000F8753F5D"
id=mschart1 style="HEIGHT: 326px; WIDTH: 651px" CODEBASE="mschart.cab"></OBJECT>
You can look this acticle if you need help.

2、 Mschart组件的一些常用属性介绍
a、charttype：图形的类型
charttype=0>三维直方图
charttype=1>二维直方图
charttype=2>三维折线图
charttype=3>二维折线图
charttype=4>三维面积图
charttype=5>二维面积图
charttype=14>饼图
b、showlegend：是否显示解说
c、titletext：标题
d、Columncount: The number of data columns
e、Rowcount:The number of data rows
f、Footnotetext:The footnote text.
g、Plot: Returns a reference to a Plot object that describes the area upon which a chart is displayed.
h、row: A row number in the current column. Rows are numbered from top to bottom beginning with 1. column: The current data column.
i、Rowlabel: The text for a row label. The label you specify sets the label for the data points identified by the Row property. This label appears along the category axis for most chart types and is used as the label for each individual pie in a pie chart. Label text may not be displayed if it is too long to fit on a chart.columnlabel: . Label text associated with a column in the data grid.
j、Data: The data point value. If the current data point already contains a value， it is replaced by the new value. The chart is redrawn to reflect the new value for the current data point.
k、ChartData: A two-dimensional array that holds the data used to draw the chart. If the first series of a multi-dimensional array contains strings， those strings will become the labels of the chart.ChartData is the default property for the MSChart control.
It is so many properities about Mschart Activex.I only introduce so much.Now，I will provide your two example to you!I wish it can help you understand it.

随着Internet技术的兴起，B/S结构的程序出现得越来越多，在Web上实现统计图表的方法有很多，相对于一般的应用程序实现比较难些。本文主要介绍Web统计图表的实现方法，对各种信息进行统计和分析，为提供决策依据，形象地表现分析结果，让信息用柱状图、折线图和圆饼图等结合数据仓库旋转分析以直观的形式表现出来！我们很多项目中都需要用到图表，查看了网上一些文章，B/S结构中大多使用了MS chart、shortGraph、Aspchart等组件实现，这些组件大多都是国外软件公司开发的，且需要Money才行，最终的效果看起来并不怎么样(个人觉得)，并且有很一些缺点，如MS chart客户端得装有Office才行，否则无法使用。另外还有一些使用Applet实现的，如Java chart工具包，这个工具包是Java写的，适用于支持Java Applet的浏览器，如果不用Java的话，一般的应用程序很难使用它们。
本文就提供一统计图表解决方案给你，当然你完全可以用于所有支持ActiveX的地方，不只是Web中。看完本文,我想你也能通过ASP、VBScript、Javascript来完成统计图表。最重要的是你可以写上 Copyright(C),yourcompany...，客户端让浏览器自动下载注册，无需安装。
下面就用Delphi简单的开发一个可以在浏览器上生成统计图表的ActiveX(用BCB开发是一样的，只是代码有点点不同而已)：
首先，打开Delphi，通过菜单File->new,在New items中选取Acitvex Form，在AcitveForm winzard中New AcitveX Name输入自定名： 如Mychart，下面的选项可以根据需要自行选定，这里只选取Include AboutBox， 这样delphi会自动生成一个关于对话框。 在Mychart窗口中放置一个Tchart组件，Tchart增加一个Bar形的Series，具体的情况可以自行设定,本文只做简单的介绍， 建议用方法动态生成Series。
在菜单view->Type Libary ,这里分别添加两个方法：
Add_data和Clear_data，作用分别是添加数据和清除数据。
Add_data方法中添加两个参数(ANum，类型：double， AName，类型：BSTR， Modifier 都设为in)
代码如下：
procedure TMychart.Add_data(ANum:Double;const AName:WideString);
begin
Series1.Add(ANum,AName,clteeColor);
end;
procedure TMychart.Clear_data;
begin
Series1.clear;
end;
设置一下Aboutbox，在Mychart窗口中加入一个TPopupMenu，用户弹出菜单看到关于对话框。 添加一个Menuitem设置Caption:="关于(&A)...", onclick代码如下：
procedure TMychart.PM_AboutClick(sender:TObject);
begin
showMychartAbout;
end;
作用是显示关于对话框然后设置TChart的PopupMenu设置为加个的TPopupMenu就可以了！
如果工程名没有更改的，编译一下生成MychartProj1.ocx，注册这个控件就可以使用了。
对于浏览器，可以用下面方法让其它自动注册它：
Delphi中通过Project->Web Deloyment Options设置Web发布选项，简单设置如下：
Target dir: c:\document and settings\administrator\桌面\chart\html
Target URL: .
Html dir : c:\document and settings\administrator\桌面\chart\html
然后通过菜单 project -> web Deploy 在 c:\document and settings\administrator\桌面\chart\html 目录下生成两个文件，一个html，另一个ocx文件。
这里更改一下HTML文件加上个ID=mychart1,后面加些VBScript代码，如下：
<HTML>
<H1> Delphi 5 AcitveX Test Page </H1> <P>
You should see you Delphi 5 forms or controls embedded in the form below
<HR><center><P>
<OBJECT id=mychart1
classid="clsid:B977D48F1-4DDA-4F00-9781-EC7BA3278CBD"
codebase=" ./MychartProj1.oxc#version=1,0,0,0"
width=538
height=350
align=center
hspace=0
vspace=0
>
</OBJECT>
<script language=VBScript>
mychart1.Add_data 110,"1月"
mychart1.Add_data 180,"2月"
mychart1.Add_data 120,"3月"
mychart1.Add_data 100,"4月"
mychart1.Add_data 80,"5月"
mychart1.Add_data 90,"6月"
mychart1.Add_data 110,"7月"
mychart1.Add_data 109,"8月"
mychart1.Add_data 108,"9月"
mychart1.Add_data 78,"10月"
mychart1.Add_data 99,"11月"
mychart1.Add_data 101,"12月"
</script>
保存后再用浏览器打开HTML文件， 怎么样？这个Chart还行吧！
然后打开VB再试试，代码与上面的VBS一样.
在ASP中使用和HTML类似，你可通过ASP取出数据，然后使用Add_data方法。
Delphi中的Chart功能非常强大，你完全可以开发适合自己需要的统计图表控件，上面只是一个简简单单的示例。
