An X-Bar-R chart is a chart used in statistical process control, designed to indicate how accurately a value in your process is being controlled.

The chart is one of the several types of analytic report you can generate in Data Explorer.

The chart is designed to show when - and by how much - a value has differed from its target value.

It is accessible from the navigation menu when you click on a single channel.

If one of the chosen channels includes the word target or setpoint, an X-Bar-R chart is created instead of a normal Scatter Plot.

For example, you could…

• Left-click on a bar-chart of one of the values you want to compare,
• Choose Compare To… from the menu,
• Pick the other value you want to compare from the pop-up list.
