title: SSRS 2012 Charts Not Rendering
body: <p>We recently upgraded to SQL Server 2012, and after a reboot a couple of nights ago, all of our charts have stopped working.  </p>
  
  <p>All charts in various reports are now showing as a broken image with a red 'x' in the top left corner when I try to view them from report viewer controls. This is happening in both the report manager and in a third-party application that uses the report viewer control to display reports.  Charts are also broken in report subscriptions that send the reports as an attached PDF.  </p>
  
  <p>However, the charts work fine from our custom web apps, which do not use the report viewer control--we have code to render the reports directly to pdf, and display them as a PDF in the web browser.</p>
  
  <p>Does anyone know of any issues with recent updates that may be causing the issue?  Or, is there something that I should add to the web.config?</p>
  
  <p>Any suggestions would be greatly appreciated.</p>
