Attn Power BI ninjas: Custom Date Range Inquiry

[Anonymous]

Greetings Power BI ninjas! I am a new Power BI user and need some assistance from the community. I am trying to create a custom date range that will go back 15 years from the date that I manually select.

Target result: I want to have a drop down selection where I pick a year, the selected year will calculate back the selected year + 15 years prior.

Current problem: The closest thing that I can get to this is a sliding date scale but my ultimate target is to just have a drop down where I can select a year and it will calculate that selected year + 15 years prior just like what the sliding date scale is accomplishing (please see screenshot below for reference)

As a new user, I am a true noob and welcome any advise. Please be advised that as a true noob, your welcomed advice might literally have to be spelled out in steps for me.

Help a brotha out pls!

Hi @Anonymous,

You can create an extra table which is unrelated to source data table, to list all available year selections.

Year selection =
FILTER (
    CALENDAR ( DATE ( 1980, 1, 1 ), DATE ( 2020, 1, 1 ) ),
    MONTH ( [Date] ) = 1
        && DAY ( [Date] ) = 1
)

Later, please add this [date] field into slicer.

Create below measure and add it to visual level filter, set its value to 1.

flag =
IF (
    MAX ( 'Sheet1 (2)'[Year] ) <= YEAR ( SELECTEDVALUE ( 'Year selection'[Date] ) )
        && MAX ( 'Sheet1 (2)'[Year] )
            > YEAR ( SELECTEDVALUE ( 'Year selection'[Date] ) ) - 15,
    1,
    0
)

Best regards,

Welcome to the Power BI dojo @Anonymous 🙂

There are probably several approachea, I think this solution should fit your need alright.

You can have a new calculated table with two columns:

- "Year anchor"  that will be your slicer

-  "Year", that will have a relationship to your date table or whatnot

This formula will generate a table where each year anchor will have 15 rows (year -15 up to year anchor)

Table =
FILTER(
CROSSJOIN(
SELECTCOLUMNS(GENERATESERIES(2000,2015,1),"YearAnchor",[Value]),
SELECTCOLUMNS(GENERATESERIES(1985,2015,1),"Year",[Value])
), AND([Year] >= ([YearAnchor] - 15), [Year] <= [YearAnchor])
)

Hope this helps!
