在web.config部分添加以下内容：

<system.web>
  <httpHandlers>
    <add tagPrefix="asp"
                 namespace="System.Web.UI.DataVisualization.Charting"
                 assembly="System.Web.DataVisualization, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/> 
  </httpHandlers>
</system.web>

<handlers>
    <remove name="ChartImageHandler" />
    <add name="ChartImageHandler" preCondition="integratedMode" verb="GET,HEAD,POST"
        path="ChartImg.axd" type="System.Web.UI.DataVisualization.Charting.ChartHttpHandler,
        System.Web.DataVisualization, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />
</handlers>

检查服务器上是否安装了程序集，并检查服务器上的web.config是否在

部分包含控件程序集和命名空间

比如说

<add tagPrefix="asp"
         namespace="System.Web.UI.DataVisualization.Charting"
         assembly="System.Web.DataVisualization, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>  

尝试以下代码：
只需从web.config节中删除以下条目：

<httpHandlers>
<add path="ChartImg.axd" verb="GET,HEAD,POST" type="System.Web.UI.DataVisualization.Charting.ChartHttpHandler,
    System.Web.DataVisualization, Version=4.0.0.0, Culture=neutral,PublicKeyToken=31bf3856ad364e35"
    validate="false" />
</httpHandlers>



还应确保该部分包含以下内容：

<system.web>
  <httpHandlers>
    <add tagPrefix="asp"
                 namespace="System.Web.UI.DataVisualization.Charting"
                 assembly="System.Web.DataVisualization, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/> 
  </httpHandlers>
</system.web>

<handlers>
    <remove name="ChartImageHandler" />
    <add name="ChartImageHandler" preCondition="integratedMode" verb="GET,HEAD,POST"
        path="ChartImg.axd" type="System.Web.UI.DataVisualization.Charting.ChartHttpHandler,
        System.Web.DataVisualization, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />
</handlers>
