Year, Quarter, Month and Week To Date are the common analysis that I seen many applications. I will share the expression to do here
First to do this your data model should have the DateField in number format by applying floor
Similar to this
Floor(DateField) AS DateNum //it will gives you one whole number to represent date
YTD - Year To Date
A date should be selected and it will look for the Starting date of the year to the selected date.
Ex: date selected is 21-03-2014 then YTD is 01-01-2014 to 21-03-2014
Expression would be
Sum({<Year=, Month=, Quarter=, Week=, DateField=, DateNum={">=$(=Num(YearStart(Max(DateNum))))<=$(=Max(DateNum))"}>} Sales)
QTD- Quarter to Date
In the place of year use Quarter
Sum({<Year=, Month=, Quarter=, Week=, DateField=, DateNum={">=$(=Num(QuarterStart(Max(DateNum))))<=$(=Max(DateNum))"}>} Sales)
MTD- Month to Date
Sum({<Year=, Month=, Quarter=, Week=, DateField=, DateNum={">=$(=Num(MonthStart(Max(DateNum))))<=$(=Max(DateNum))"}>} Sales)
WTD- Week to Date
Sum({<Year=, Month=, Quarter=, Week=, DateField=, DateNum={">=$(=Num(WeekStart(Max(DateNum))))<=$(=Max(DateNum))"}>} Sales)
if you want you can set a variable value as 'Year', 'Month', 'Quarter', 'Week', lets say vToDate and go with single chart and single expression
Sum({<Year=, Month=, Quarter=, Week=, DateField=, DateNum={">=$(=Num($(=vToDate& 'Start(Max(DateNum))')))<=$(=Max(DateNum))"}>} Sales)
Will keep your expression simple
