Trend Line for Bar Chart Tracking 5% Reduction on Last Year's Totals

Hi All,


I need to add a trend line to a bar chart which shows the targeted 5% reduction against last year's totals. So if last year's total was 100 the trend line for this year needs to be at 95. 


The trend line also needs to filter by Type and Sub-Type 1 & Sub-Type 2  


How can I do this please?

@owdtelly , Try like , with time intelligence and date table


95% = CALCULATE(sum('order'[Qty]), previousyear('Date'[Date]))*.95


95% = CALCULATE(sum('order'[Qty]), previousyear('Date'[Date]),all('Order'))*.95


To get the best of the time intelligence function. Make sure you have a date calendar and it has been marked as the date in model view. Also, join it with the date column of your fact/s. Refer :
