C1WebChart 对图形化处理还可以。以下图如下：
A：折线图：
B：柱形图：
C：面积图：
D：饼图：
E：折线图（3D）
F：柱形图（3D）
G：面积图（3D）
H：饼图（3D）
完成这些功能。需要以下条件。
1：引用相关组件(C1.Common.dll、C1.Web.C1WebChart.dll、C1.Win.C1Chart.dll)
2：配置web.config
<system.web>
<httpHandlers>
<add verb="*" path="c1chartimage.aspx"
type="C1.Web.C1WebChart.ImageHttpHandler,C1.Web.C1WebChart"/>
</httpHandlers>
......
</system.web>
3：详细代码如下：

设置 compilation debug="true" 以将调试符号(.pdb 信息)
插入到编译页中。因为这将创建执行起来
较慢的大文件，所以应该只在调试时将此值设置为 true，而在所有其他时候都设置为

<!-- 应用程序级别跟踪记录
应用程序级别跟踪为应用程序中的每一页启用跟踪日志输出。
设置 trace enabled="true" 可以启用应用程序跟踪记录。如果 pageOutput="true"，则
在每一页的底部显示跟踪信息。否则，可以通过浏览 Web 应用程序
根目录中的 "trace.axd" 页来查看
应用程序跟踪日志。
-->
<trace
enabled="false"
requestLimit="10"
pageOutput="false"
traceMode="SortByTime"
localOnly="true"
/>
<!-- 会话状态设置
默认情况下，ASP.NET 使用 Cookie 来标识哪些请求属于特定的会话。
如果 Cookie 不可用，则可以通过将会话标识符添加到 URL 来跟踪会话。
若要禁用 Cookie，请设置 sessionState cookieless="true"。
-->
<sessionState
mode="InProc"
stateConnectionString="tcpip=127.0.0.1:42424"
sqlConnectionString="data source=127.0.0.1;Trusted_Connection=yes"
cookieless="false"
timeout="20"
/>
<!-- 全球化
此节设置应用程序的全球化设置。
-->
<globalization
requestEncoding="utf-8"
responseEncoding="utf-8"
/>
</system.web>
<appSettings>
<add key="DBConnectString" value="server=(local);User ID=sa;Password=sa;database=CSDN" />
