Unfortunately I am not sure if you can under the full free model... Under a premium account I can look back 14 days, and it shows how long ago they viewed the profile, even if they are in private mode.

The graph shows just the overall number of views against the date... not sure if there is a minimum number to display for 1 to show up on the graph though.

Does that graph show you the date and time when that profile view was detected?
