TOPN current month x quantity Tickets Last Month

Good Morning. I need help.

I Have one fact table named F_incidents.
I created 3 measure listed below:

-Qtde Raised sem vazio= CALCULATE(COUNTROWS(F_Incidentes);F_Incidentes[CATEGORIA_KPI]="Raised";F_Incidentes[COD_SEQ_SISTEMA]>0)

Raised TopN = if(HASONEVALUE(dTOPN[TOPN]);if(rankx(all(D_Sistema[SISTEMA]);[Qtde Raised sem vazio])<=values(dTOPN[TOPN]);[Qtde Raised sem vazio];blank()))

Rank = rankx(all(D_Sistema[SISTEMA]);[Qtde Raised sem vazio])

With these mesuares I created the [TOP5 System (ticket number) x November (Selected in calendar filter)] Bar Graph.

This graph shows top5 Systems with the bigest quantity of tickets per month (I selected the month in a filter). (Like first grah in a example.

Now, I need your help to include in the same bar graph an additional information (Column):

Quantity of tickets considering the previous month considering that one selected in a filter.

Example.

I Choose in a calendar filter: November.

First graph shows top5 system x November.

The second graph need shows top5 System (november) x Quantity tickets previous month (October ins this example).
