Modify range of graph? (+Datepicker handling is confusing..)

Hi,

I was wondering, is it possible to modify the date range of the graphs?
It’s a bit confusing, when you select the period “year” and you get a graph starting at 1999, when there’s only data available for 2010. Same thing with months etc.

Additionally, I think the word “Period” in the datepicker is a quite confusing, since it isn’t really the period, it’s just the way how to group the data. A regular user would expect when he chooses “Month”, he gets the data from all days from 1-31 of the selected month.
Are there already plans to improve this? I think I’m not the only one with this problem.
