charts not displaying on the server

Question

Hi All,

I am displaying two line graphs and two pie charts on my web page. I am not sure why is it happening, but sometimes I see the charts when I run my applications and sometimes I don't. below is my web.confg file settings.

<?xml version="1.0"?>
<configuration>
  <system.web>
    <authorization>
      <allow roles="ANALYST"/>
      <deny users="*" />
     
    </authorization>
    <httpHandlers>
      <add path="ChartImg.axd" verb="*" type="System.Web.UI.DataVisualization.Charting.ChartHttpHandler, System.Web.DataVisualization, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" validate="false"/>
    </httpHandlers>
  </system.web>
  <system.webServer>
    <handlers>
      <remove name="ChartImageHandler"/>
      <add name="ChartImageHandler" preCondition="integratedMode" verb="*" path="ChartImg.axd" type="System.Web.UI.DataVisualization.Charting.ChartHttpHandler, System.Web.DataVisualization, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"  />
      
    </handlers>
    
    
  </system.webServer>
  <appSettings>
    <add key="ChartImageHandler" value="WebDevServerUseConfigSettings=true;privateImages=false;storage=file;timeout=20;dir=c:\test\;"/>
  </appSettings>
</configuration>

apart of this, I have System.web.datavisualization.dll in my bin folder and I am running the application on window server 2008 R2. The whole application is devleoped in .net 4.0. I am not getting any error message. I see the graphs images in the C:\Test folder where I am putting the images, but not on the web page.

Thanks.
