Custom Trend Line on Bar Chart
Hi noob123newbie ,
You can update the formula of measure [Trendline] as below, please find the details in the attachment.
Trendline = VAR _curmonth = SELECTEDVALUE ( 'Sales'[Month].[MonthNo] ) VAR _curyear = SELECTEDVALUE ( 'Sales'[Month].[Year] ) VAR _date = EOMONTH ( DATE ( _curyear, _curmonth, 1 ), -1 ) VAR PreviousMonthSum = CALCULATE ( SUM ( 'Sales'[Value] ), FILTER ( ALLSELECTED ( 'Sales' ), YEAR ( 'Sales'[Month] ) = YEAR ( _date ) && MONTH ( 'Sales'[Date] ) = MONTH ( _date ) ) ) RETURN IF ( ISBLANK ( PreviousMonthSum ), BLANK (), PreviousMonthSum * 1.2 )Best Regards

According to your description, a measure for the line should be
Trend_measure = [your measure ]*1.2
