Try :

if(SUM(sales),SUM(sales), linest_m(total aggr(if(SUM(sales),SUM(sales)),month),month)*

only(month) +linest_b(total aggr(if(SUM(sales),SUM(sales)),month),month))

‌Similar to omarbensalem recommendation, I created a simple app that shows how to do this in Qlik Sense in a couple of different ways. It can be accessed here:
