Need help to exclude data

I'd suggest adding a column to your table such as this, then filter your chart to "Yes":

DisplayOnlyValidPeriods = 
IF(Table1[Date Difference] <= (2019 - Table1[Account Open Year]) * 12 + 5,
    "Yes",
    "No"
)

Presumably, this is a data set that will be occasionally updated. As such, you'll probably want to update the hard-coded 2019... logic to something that uses the current year/month minus whatever lag you want to include in the reporting.

CoalesceIsMore Thank you so much for your answer. I have managed to get the desired result by using your calculated column but I have amended a little:

DisplayOnlyValidPeriods = 
IF('Main Query'[z. Date Difference From Account Open to Month] <= (Year(Max('Main Query'[Month_Start_Date]))-1 - 'Main Query'[Account_Open_Date - Year Only]) * 12 + 'Main Query'[Max month],
    "Yes",
    "No"
)

now I am planning to add a calculated table which will only store max month from my date. 

Thanks for all the help.
