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 123Count on your site. The number at the bottom of each bar is the percentage of visitor sessions received for that day since the graph was created. 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.
