In the week view, all graphs show a slump at the end. The sparklines on the overview page have big fat red downward arrows with numbers like “-80%” next to them. But that’s an artifact. It’s only because today is the second day of the week. The graphs compare the data for 1 1/2 days of the current week to the data for the whole 7 days of last week.
I’m not sure how to handle this properly. Maybe the last segment of the graphs could be dotted and show a projection for the current period based on the available data:
projection_visitors_current_week = visitors_current_week_to_date / available_days_current_week * 7
(available_days_current_week is a float)
