# 2019 Week 8: What percentage of products make up 80% of sales?

For this week’s workout, we look at one of my favorite chart types, the pareto. I love the pareto chart as a data exploration resource, and also as a powerful analytic resource. If you aren’t familiar with the pareto, the purpose is to see what % of x, makes up what % of y, with the common assumption that 20% of the x makes up 80% of the y. This week’s workout takes this chart a couple steps further by identifying the point where the % of x crosses 80% of the y. We will also give our users the power to drill into the actual values of any subset of the x. A key piece of this challenge is using Tableau’s built in functionality to your advantage, try and build this viz with two or less written calculated fields!

Have fun!
