I've created a pivot table that shows department, month, and year dimensions and has three expressions for the totals columns. I want the chart to only show 3 months of data, with this always being the most recent three months of data.
Can this be done with a calculated dimension rather than set analyis? I think I would need to add a set expresssion to ALL three expressions right? I'd rather avoid that if possible due to formatting in the expression to make it show as hh:mm:ss.
