Show cumul only in last month in graph

[Juju123]

Good morning,

I have the following problem that I cannot resolve.
I have this type of chart.

I want to display the cumulative value only for the last month.

For example, if I select the company B130, I want all the values ​​and display the cumulative total with a point for the month of September.

Likewise, if I select company B220, I want to display the cumulative total with a point for the month of August.

Here is my DAX formula:

Cumul = IF(MONTH(SELECTEDVALUE('Entity (Feuil1)'[Date]))=MONTH(TODAY()) && YEAR(SELECTEDVALUE('Entity (Feuil1)'[Date]))=YEAR(TODAY()),
     Calculate (
         sum('Entity (Feuil1)'[Order]),
         FILTER(
            ALLSELECTED('Entity (Feuil1)'[Date]),
            ISONORAFTER('Entity (Feuil1)'[Date], MAX('Entity (Feuil1)'[Date]), DESC)
         )
),BLANK())

My data it this : 

Entity	Date	Order
B130	30/04/2020	1
B130	12/05/2023	1
B130	22/06/2023	3
B130	12/12/2023	2
B130	01/08/2024	2
B130	14/09/2024	1
B220	01/02/2023	1
B220	04/07/2023	1
B220	05/03/2024	1
B220	11/08/2024	2
B220	02/06/2024	1

Thank you in advance for your help

@Juju123 Hi! Try with:

Cumul =
VAR LastMonthDate = CALCULATE(
MAX('Entity (Feuil1)'[Date]),
ALLEXCEPT('Entity (Feuil1)', 'Entity (Feuil1)'[Entity])
)
VAR LastMonth = MONTH(LastMonthDate)
VAR LastYear = YEAR(LastMonthDate)

RETURN
IF (
MONTH(SELECTEDVALUE('Entity (Feuil1)'[Date])) = LastMonth &&
YEAR(SELECTEDVALUE('Entity (Feuil1)'[Date])) = LastYear,
CALCULATE(
SUM('Entity (Feuil1)'[Order]),
FILTER(
ALLSELECTED('Entity (Feuil1)'[Date]),
'Entity (Feuil1)'[Date] <= LastMonthDate
)
),
BLANK()
)
