Set analysis calculates one set per chart, not a set per dimension value. If you use month as a dimension and you want a 3-month accumulated sum then using set analysis is very tricky. I find it easiest to create a new table that links each month value with the last 3 months. See this document for more information: Calculating rolling n-period totals, averages or other aggregations
