I am having a spot of bother around a set analysis.
I have a line chart and want to display values as at the same time in the previous year. However, my issue surrounds the selected variable. For example, the selected variable (Trimester) displays as follows: 2012-2 (denoting 2012 as the year and 2 as the semester). I really don't want to split up the variable into 2 user selections/fields (Year and Semester) and run set analysis against these as it will add a layer of possible user error.
