it would be nice, if I could add points or periods of time to all request and visitor charts etc.
The idea is, to have a list of events (with start / end time) e.g. press conference, fair or any other event that may be responsible to in- or decrease your requests / visitors.
If those events where a layer over your request chart (line or rectangle) it could ease the way to analyze peaks or other abnormality.
