Pls update to the latest version of the reader and check . It should work.
It is strange because it doesnt show on some charts on my laptop - but when I move it on a bigger screen they show up fine.
This was not happening before and I have not made any changes.
Is there anything else I can try - I only have access to v10.2 currently.
May be the dashboard size. You can download the latest version of the reader which is free. If you can attach the workbook ,I can check.
