R chart:

• These graphs are employed to distribute the measured data.

C Chart

• The number of flaws per unit of a product is studied using the C chart.

P chart:

• A lot of attributes are used in these visualizations.
• These are employed in assessing fractional defects.
• They are employed to locate samples that are outside of permissible ranges and lack quality control.
