Filters are not being displayed well (not Acumulative)

[Anonymous]

Hey! I am very new at Power BI and I love it but, there is some kind of problem (or maybe I am doing something wrong) when I select the some data in a chart (i.e. number of sales this month) and with that selected I want to select other related data from other chart on the report (i.e sales by electronic department), it will give me the sales of the electronic department of ALL entries not only for this month (filter 1).

My question is, how could the program keep the previous filters and no loosing them across the selections?

Thanks!
