Create a visual of data evolution month over month

[samira]

Hello, I want to build a visual that shows total count over the span of a year. My issue is that our data ets deleted after 28days, and the data is too large, so it's impossible to show a year worth of data. The table below represents what my table would look like in PowerBi.

Does anyone have a workaround on this?

Month	Count
January	2000
February	2000
March	2000
April	4000
June	3000
July	9000
August	12000

@samira , What exactly you need is not very clear. MOM or MOYM you can use time intelligence

But you data is refreshed after 28 day and you need create a snapshot in power bi, you need check for dax append method

DAX append
