Return/generate value based on date range

[MoCPA]

Hello Community, 

I need to right a measure that generate value based on date range. So basically i've calendar table and data input table. 

Data Input

Start Date	End Date	Amount
1/1/2020	12/31/2021	100

So the requirement is to put this on line chart that has periods from calendar table on x axes and we want a line shows the amount the Amount on every month within that period. 

Any ideas other that building a table to spread the amounts of rows?

Hi @MoCPA ,

I suggest you to inactive or remove the relationship between the input table and calendar table. Then create a measure to filter your visual.

Filter = 
VAR _START =
    SELECTEDVALUE ( 'Data Input'[Start Date] )
VAR _END =
    SELECTEDVALUE ( 'Data Input'[End Date] )
RETURN
    IF (
        MIN ( 'Calendar'[Date] ) >= _START
            && MAX ( 'Calendar'[Date] ) <= _END,
        1,
        0
    )

Add this measure into visual level filter and set it to show items when value = 1. Result is a below.
