##### Calculating the Statistical State

Calculating the Statistical State – You can calculate the statistical state of variables by selecting multiple variables and clicking the Calculate Status icon from the toolbar or by selecting Monitor | Calculate Alarms. The calculation process determines whether or not the selected variables are in or out of tolerance, and what their control limits are. The statistical state of the variables is then displayed by showing each variable in one of the following default colors.

Green - Uncalculated variables or those that have not out of tolerance or out of control conditions after calculation.

Orange - Variables that failed at least one control test are considered out of control.

Red - Variables that have at least one measurement that is out of tolerance.

Purple - Variables that are both out of control and out of tolerance conditions.

You can easily configure these colors by clicking the Properties icon and using the General tab inside the dialog box that appears. See "Changing Properties" for more information.
