How to compare different products sales in different date?

[DonnaC]

Hi All,

I want to compare different products sales. Those products were launched on different dates, so they have different first sale month, second, third and so on, just like that sample showing in the table below. Now I want to compare different productions' first, second until the last month sales in line chart, similar with the chart below. How could I create procedure with DAX in Power BI?

Thanks!

Donna

@DonnaC , You can create a new columns

first sales date = minx(filter(table, [product] =earlier([product])), [sales Date])
month since first sales = datediff([first sales date],[sales Date],month)
