Problem rendering dates on chart lines

[Syndicate_Admin]

Hello

I'm working on a report with data generated by another area. The problem I find is that when I try to represent linearly in a graph the evolution of several parameters over the months I am represented the accumulated per month. That is, although I want to see the monthly evolution over 3 years, I get only 12 months and each one adds up to the total of that month during the three years.

I don't know if there is a way to modify it without having permissions to modify the origin of the data.

Thank you

@Syndicate_Admin , try a measure like this with date table, and use month /period from date table

Cumm Sales = CALCULATE(SUM(Sales[Sales Amount]),filter(allselected('Date'),'Date'[date] <=max('Date'[date])))
