I see that pie charts use only top 5 of MOST used things. To combine 3 months you need to sum all the data for all months and get TOP5 of the sum. I use query function for this:

=query({B2:C6;F2:G6;J2:K6},"select Col1, sum(Col2) group by Col1 order by sum(Col2) desc limit 5 label sum(Col2) ''",0)

You need to repeat this for each top5 set.

Then you make a new pie chart based on combined data:
