Pivot chart from monthly to yearly

[gengiskhan]

Hi there,
I found a passionate office template to deal with expense monitoring

I'm get interest to understand how in the tab "Riepilogo mensile" would be possible to get the chart (or the pivot table below where is sourcing the chart) also with year label of the expense.
As you would see the graph (and table below) are representing month data which concentrate information of different years .

Thank you for your help,
