My problem that i need to use a filtre that :

If month= 'Janv' ,  the filter display  all value of location when moth=Janv

if month=Févr , the filter display  all value of location when moth='Janv' and month=Févr

if month= Mars,  the filter display  all value of location when moth='Janv' and month=Févr and month= Mars

To display  location i use a qlik map .

thanks

Not an issue. Use set analysis . i am assuming you have no dates just the month field.
step 1 add another column called MonthNum. Use a map to assign number value to each month
step 2 in your expression something like Sum({<MonthNum={"<=$(MonthNum)"}, Month=>}Sales)
basically set analysis says ignore Month selection and get all monthnums below the selected month
