there are at least two ways:

save current month in a variable - vMonth,
vYearStart = in your set analysis, this is your year to month
{<DateField={">=$(=yearstart(vMonth))<=$(vMonth)"}>}

prev year to month, just addyears -1:

{<DateField={">=$(=addyears(yearstart(vMonth),-1))<=$(addyears(vMonth,-1))"}>}

to make this faster, you can create 4 variables: current month, 1st day of the current year, prior year month, 1st date of prior year:
vMonth

=yearstart(vMonth)

=addyears(vMonth,-1)

=addyears(yearstart(vMonth),-1)

2nd way is to build a bridge that associates the current month with all the dates from YTD and prior YTD.

this is useful when you have huge volumes of data and you dont want your UI to have to do the calculation.
