This topic explains how to add a chart to your Web application both at design time within Visual Studio and programmatically.

Refer to the following help topic to learn how to add a chart to a Web page at design time within Visual Studio: How to: Add a Chart to a Web Application.

Note that after a chart is first added to your web application, its Web.config file is affected. The following module is added to its XML code:

Web.config

<system.web>
    <!-- The following lines will be added to the system.web section. -->
    <httpModules>
        <add type="DevExpress.Web.ASPxHttpHandlerModule, DevExpress.Web.v20.2,
        Version=20.2.13.0, Culture=neutral, PublicKeyToken=_"
        name="ASPxHttpHandlerModule" />
    </httpModules>
</system.web>
    <!-- And, the following - to the system.webServer section. -->
<system.webServer>
    <validation validateIntegratedModeConfiguration="false" />
    <modules>
        <add type="DevExpress.Web.ASPxHttpHandlerModule, DevExpress.Web.v20.2,
        Version=20.2.13.0, Culture=neutral, PublicKeyToken=_"
        name="ASPxHttpHandlerModule" />
    </modules>
</system.webServer>

Refer to the following help topic to learn more about the ASPxHttpHandlerModule: ASPxHttpHandlerModule.
