Hello! First time poster:
I am trying to make a date slicer, but I want the date to be dynamic, depending on another piece of information (earliest villain date):
I want to have a graph on the report view that gives each Identifying number as a choice
When you click on that, I have measures to show how many "Run in with cops" before and after the "Earliest villain date"
What I want to do now, is be able to add a slicer based on their "Villain date" to zoom in on the month, 6 months and year surrounding their "Villain date".
Each villain date is unique to the ID, some don't have an earliest villain date at all (so they would not appear on the graph on the report view)
Is there a way to add a slicer/button to show 1month/6 months/1 year before and after their Earliest villain date?
(I hope that makes sense, please let me know how I can clarify)
Okay, see attached file for a solution:
Add a Custom Column to your data table using Power Query > Add Column > Custom Column
Duration.Days( [Run in with Cops] - [Earliest Villain Date])
Then create a new measure:
Run in is within Selected Time Period =
VAR _DaysWithin = SELECTEDVALUE( 'Time Slicer'[Days] )
VAR _Result = COUNTROWS( FILTER( 'Table', ABS('Table'[Days Since Earliest Villain Date]) <= _DaysWithin) )
RETURN
IF( MAX( 'Table'[Days Since Earliest Villain Date] ) = BLANK(), BLANK(), _Result )
I also added a date table for good practice, but you don't need it yet here: https://excelwithallison.blogspot.com/2020/04/dimdate-what-why-and-how.html
