View the Metrics R-bar chart

You can use the R-bar chart in scenarios where you measure the output in terms of a variable such as height or weight. As with the X-bar chart, the R-bar chart only plots one point per configured samples series; however, the plotted value is the difference between the maximum and minimum value in the sample series. This type of chart is useful to determine if there are large changes in your KPIs while keeping the average at a certain level.

To view the Metrics R-bar chart

1. Select Metrics on the Select Module panel.

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

3. In the Chart panel, select R-bar chart.
