Ratio of the dynamic filter

[sakamotothais]

Good morning people Can someone please help me?

I have a date slicer filter and another day of the week filter.

In the chart when filtering the day of the week, it shows the two days refers to the week

(For example Friday, presents days 21 last week and day 14 of the week behind)

I would like a formula that I can measure the proportion between them.

Example The date value of day 21 divided by date value of day 14.

And leave dynamic whenever I want to filter other days of the week.

The account would be: DIVIDE (Day 14 - Day 21) / Day 14

And it may at some point be divided between three dates, if I look Friday and get from the date of the current week day 28.

It's possible?

thanks

What is the formula for three dates? (Day14- Day28)/Day 14? So the the equivalence could be (Earlist date - Latest date)/Earlist date, right? Then try

earlist value = CALCULATE(SUM('Table'[value]),FILTER('Table','Table'[Date]= MIN('Table'[Date])))

latest value = CALCULATE(SUM('Table'[value]),FILTER('Table','Table'[Date]= MAX('Table'[Date])))

your Fomula = DIVIDE([earlist value]-[latest value],[earlist value])

See more details in the attached pbix file.
