How to add activity per day on profile page?

Hi there. Am new to elgg and i have installed the plugin advanced statistics. I tried to add "Activity per day" as it appears on the admin to the profile page but the ajax loader keeps spinning without displaying anything.

Can some one throw some light why it is  so. Thanks
