Failed to download chart or image

Failed to download chart or image

issue: After create chart and upload to site. I got error "failed to download chart or image"

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

Solution: To solve the issue, Please take steps as 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
