Displaying more than 6 items in piecharts

I have about 9 results that I could like to display on a piechart in my ‘events’ section. The issue is that a good number of them are aggregated into the ‘other’ section which takes up nearly half the piechart. Is it possible to increase the number of results displayed that aren’t in the ‘other’ section as it looks like there’s space for more on the piechart.
