Dynamic TOPN

Hi rodrigosrm2 

Calculated tables and calculated columns are not able to be updated by slicers/filters in the report. So your Group column is not dynamic. 

I create a new table in your model, which summarizes on Year and Game at the same time. 

New Table = SUMMARIZE(fTwitchData,fTwitchData[Year],fTwitchData[Game],"Hours_watched",SUM(fTwitchData[Hours_watched]))

Then add Rank and Group columns in the new table. It ranks games within every year. 

Rank = RANKX(FILTER('New Table','New Table'[Year]=EARLIER('New Table'[Year])),'New Table'[Hours_watched],,DESC,Dense)

Group = IF ( 'New Table'[Rank] < 6, [Game], "Other" )

Link Calendar table to this new table on Year columns (many-to-many, single filter direction: calendar table filters New Table).

Then use Group and Hours_watched columns from this new table into the chart.
