Pareto filtering

The Pareto principle (also known as the 80-20 rule) states that, for many events, 80% of the effects come from 20% of the causes.

This is a useful feature when a dimension, like customer, has a large number of categories and you want to identify the 20% of your clients who brings 80% of your sales. Filtering based on this principle automatically groups the categories that amount to less than 20% of a row or column total into ‘other’ category.
