Graph Display by Week calculates wrong numbers if add an annotation column on a specific date
I have a chart displaying conversion rates per day. In the section where any viewers can change the "graph by" setting, if this is changed to weekly then wierdly the graph displays the week that includes the annotated date twice in the x-axis and also calcualtes the weekly conversion wrong. This problem disappears as soon as I delete the annotated date column.
Any ideas on how i can fix this issue?
