This graph shows the daily traffic on your site since you first installed Web-Stat on your site. Each bar represents one day, and the bar's height represents the total number of visitor sessions on your site during that day.
After 30 days of traffic analysis a red line will appear on the graph. This line represents the rolling average of your traffic over a 28-day period ; it smooths out daily extremes and shows how your average traffic evolves over time.
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).
