Issue

After creating a chart and uploading it to the site, the error "failed to download chart or image" appears.

Cause

In Excel Service, there is a file size limit in the configuration. Large graphs may cause this to fail. By default, it is 1 MB. If a chart is bigger than that it won't render.

Solution

To solve the issue, please use the steps below:

  1. Go to Central Administration->Application management->manage service applications->Excel services application->Trusted File Locations.
  2. Edit the Trusted File Location, change Maximum Chart or Image Size to 50 and Maximum Concurrent Queries Per Session to 50.
  3. Go to Global Settings, change Memory Cache Threshold to 95.
