    Ok here is how i made it work..

    First i found the System.Web.DataVisualization DLL’s which were present in the assemblies of MS chart control folder in my program files. i copied these to my bin folder on the local host and then published it..

    then on server side i made a directory in C drive as TempDump and made the following change in web config file..

    <appSettings>
  <add key="ChartImageHandler" value="storage=file;timeout=20;dir=c:\TempImageFiles\;"  />
 </appSettings>

    I changed this to

    <appSettings>
  <add key="ChartImageHandler" value="storage=file;timeout=20;dir=c:\TempDump\;" />
</appSettings>

    and everythig worked perfect..

    thanks
