@nouha,
It looks like the sample provided by you is restricted and requires permission. Can you please make the image / sample public so that we can access it?
If the Google Drive link shared contains an image, can you kindly create JSFiddle reproducing the issue you are facing & share it with us so that we can look into the code / chart-options being used, understand the scenario better and help you out?
