Showing group of dates filtered with slices

[Anonymous]

Hello all,

I would like to get a line chart of the numbers of sales for a period like this one

But I'd like to know if I can get the same, filtering the date in a list or dropdown slice,

instead of a range of dates.

This is the measure I'm using:

sales =

CALCULATE(countrows(sales);FILTER(sales;sales[salesdate]>=sales[salesdate]-7 && sales[salesdate]<=sales[salesdate]))

Thanks in advance for your help
