Pareto chart
The Pareto chart is a special type of bar chart or histogram, and is one of the seven quality tools, named after Vilfredo Pareto. It is an analytical tool that graphically demonstrates the Pareto principle or the 80–20 rule. It is used to view causes of a problem in order of severity or impact from largest to smallest.
The categories are placed along the bottom x-axis in order from largest to smallest, and the quantity or cost are placed on the y-axis. Often times, a line is drawn against the opposite y-axis to represent the cumulative impact %.
