A p-chart is a characteristic controlling chart that is used with information collected in varying length subsets. Since the size of the subgroup varies, it displays a percentage of nonconforming products instead of the exact number. P-charts depict how the procedure evolves.

The procedure property (as well as a feature) is usually expressed as a no or yes, failed or passed, go or no proceed. In statistical process control, a p-chart (also known as a p-control chart) is used to chart the percentage of faulty goods.
