I can't see a graph on the health tab. Neither on 7,30 days nor all days. I have a BC-1000 and a FR60-watch and have uploaded 4 files for the last 4 days.
Jollycity, worth trying a possibly simple solution. See the 'broken page" button just to the right of your address field in the top toolbar of IE? That button toggles on compatibility view for webpages that might be having some issues displaying properly in the most recent version of IE. Try clicking on that to toggle on compatibility view and see if that might clear things up...?
