It is a good communication tool that describes the data in a simple and easy-to-read bar diagram. The cumulative percentage line starts at the first (highest) bar, and extends to the last bar to help you assess the added contribution of each category. As you can see, the Pareto chart also changes dynamically as per your product categories. A Pareto chart is one of the best ways to emphasize the major factors to anything that can be counted and categorized.. Read our guide on the Pareto Principle and Pareto Analysis for more information on these key quality improvement concepts. The seventh step is to construct a chart with the left vertical axis scaled from 0 to at least the grand total. So it should go from the 9.2 on the x-axis up to the orange line. As you can see, the Pareto chart also changes dynamically as per your product categories. Source. You can contact me through this contact form.
