How to Plot Active Transactions by Month

Hi Jeromec ,

I have built a data sample for test.

1. Firstly you need a new table with all year-month period between Start Date and End Date

Year Month =
DISTINCT (
    SELECTCOLUMNS (
        CALENDAR ( MIN ( 'Table'[Start Date] ), MAX ( 'Table'[End Date] ) ),
        "YearMonth",
            YEAR ( [Date] ) * 100
                + MONTH ( [Date] ),
        "Year", YEAR ( [Date] ),
        "Month", FORMAT ( [Date], "mmmm" )
    )
)

2. Create a count measure:

Count of each month =
CALCULATE (
    COUNTROWS ( 'Table' ),
    FILTER (
        'Table',
        YEAR ( [Start Date] ) * 100
            + MONTH ( [Start Date] )
            <= MAX ( 'Dates Table'[YearMonth] )
            && YEAR ( [End Date] ) * 100
                + MONTH ( [End Date] )
                >= MAX ( 'Dates Table'[YearMonth] )
    )
)

3. Create a Stacked column chart, and in order to get the correct sorting, please drag the YearMonth field to the Tooltips pane, below is the final output:

Or if you are still confused about it, please provide me with more details about your table and your problem or share me with your pbix file after removing sensitive data.
