This graph shows what share of your weekly traffic is received by each day of the week. Each bar represents one day, and the bar's height represents the percentage of the weekly traffic received by that given day since you first installed Web-Stat on your site. The number at the bottom of each bar is the percentage of hits received for that day since the graph was created or last reset. You can use this information to find out, for instance, what your slowest days are in terms of traffic and arrange to do site maintenance on these days.
Important Note : by default, your account is set to 'test mode' in which a visit is counted every time your page is loaded. If the same visitor reloads your page 5 times in 30 seconds, then 5 visits will be counted (this is done to allow you to test the counter after installation). In order to get more meaningful stats, you should set your account to count 'visitor sessions' by selecting 'Type of Tracking -> Visitor Sessions' in the Control Panel. This ensures that a visitor loading your page several times in a row during the same browser session is only counted once (if that person comes back to your site 30 minutes or more after leaving it, a new visitor session will be counted).
