Check the display options for graph editor. If you are unsure of the UI type graph editor in the Search Help field at the top right corner of AE and check out the community resources.
If your AE is up to date and if you have had this working before and you are an experienced AE user then give us system, AE and OS details down to the last decimal point so we can help.
