Modify the confidence limits for T²-Generalized Variance Chart

In These percents, enter one or more values to display additional confidence limit lines on your control chart.

Use proportion values (between 0 and 1) or percent values (between 1 and 100).

You can specify bounds for the confidence limits. If the calculated confidence limit is farther from the center line than the value that you specify, Minitab displays the bound instead of the confidence limit. Minitab labels the lower bound as LB and the upper bound as UB.
