Create a Pareto chart based on the information below. Basically, a Pareto chart is a bar chart. Named after Wilfredo Pareto, this type of chart is similar to a bar chart but shows categorical (discrete) data arranged in order of highest frequency to lowest frequency. From this chart, we can say that 67% of problems are due to Res 1, Res 2, and Res 3. 2. Step #5 – Right-click on the cumulative total line (in red) and choose format data series.
