      How to set up a regression line or trend line show the recent 3 months in a 12 months bar chart?


      In particular, below graph show me all possible 12 months, but I only want to take show 3 months trend line? What is the possible solution?


      linest_m(total aggr(if(sum([Cash_Payments]),sum([Cash_Payments])),Month),Month)*              

      +linest_b(total aggr(if(sum([Cash_Payments]),sum([Cash_Payments])),Month),Month)


      I tried changing only({3}Month, but the regression won't show up anymore if it changes. Please help.
