Time based graph filled not only per day
We got some time based graph that are not per day (like in sale reporting) but by month or year.
The clients fill a value for each day in the graph but I think we should have a way in the XML to say that it should filled per month, year etc. Indeed I think we should define the parameters passed to relativedelta. For sao, I find that c3 manage that correctly as it does not create tick for the hole.
