Any help? Idea? Combined chart

[antoniodneto]

Hi guys,

I have a combined chart with bars and lines, where I display my laste 12 months.

My expression is 

SUM( {<
DATA={">=$(=MAX(DATA,13)) <=$(=MAX(DATA))"}
>}
RISCO_TOTAL)/1000000

Now I'm trying to make a different insight for example.

My last month is Jun/19 , so I want to show something like Dec/17 (whole year acumulated),Dec/18 (whole year acumulated), first trimester (jan/19,feb/19,mar/19 accumulated) and open last 3 months apr/19,may/19 and Jun/19.

As my picture below:

Is it possible? Tks guys!!
