View the Energy Pareto chart

A Pareto chart is a type of chart that contains both bars and a line graph, where individual values are represented in descending order by bars, and the cumulative total is represented by the line.

The left vertical axis is the frequency of occurrence, but it can represent cost or another important unit of measure. The right vertical axis is the cumulative percentage of the total number of occurrences, total cost, or total of the unit of measure. Because the reasons are in decreasing order, the cumulative function is a concave function. The purpose of the Pareto chart is to highlight the most important among a set of factors.

The Pareto principle (also known as the 80–20 rule, the law of the vital few, and the principle of factor sparsity) states that, for many events, roughly 80% of the effects come from 20% of the causes.

In other words, a small number of causes can often account for a large portion of the problems. If you focus your efforts on the vital few causes, it is usually a better use of valuable resources. This chart has drill-down analysis capability.

To view the Energy Pareto chart

1. Select Energy on the Select Module panel.

2. In the Location pane, select a location in the Plant hierarchy that contains an Energy reporting point. The data in the Results grid updates to reflect that location.

3. In the Chart panel, select Pareto chart. For more information on the chart options, see Energy Pareto chart options.
