dc.js generate a pieChart with top 5 values

[Steven Natera]

I'm visualizing a drug database of 200 entries. I've created a piechart using DC.js to show the frequency of each drug. The pie chart is cluttered with drugs that appear once.

I want to adjust this pie chart so that it visualizes the top 5 most used drugs i.e. the top 5 biggest slices of the pie chart.

Is there a way to use the .group() or .reduceSum() methods so only the biggest pie chart slices are shown?

Use the functions of the Cap Mixin, which is a base of the pie chart.
