Specify miscellaneous default settings for control charts. The changes you make to the defaults remain until you change them again, even after you exit Minitab.
When last row of data causes a new test failure for any point
  • Change color of chart: Change the background color of a control chart when the final row of data causes a test failure or is out of control.
    • Color: Specify the color to change the background color of the control chart to.
Display control chart results in Session window
Display control chart test results in the Session window.

If the data change, the test results are not updated in the Session window.

Use rounded values for Box-Cox transformations when possible
Display a rounded λ (lambda) value for Box-Cox transformations on Box-Cox plots. Minitab rounds the λ value to the nearest integer, 0.5, or -0.5, which are commonly used λ values.

If the confidence interval for λ does not contain a rounded value, Minitab does not use a rounded value even when you select this option.

Display control limit / center line labels for all stages
If a control chart includes stages, display control limits and center line labels for each stage.
Specify the default distribution for T Chart
Specify whether to base calculations for T charts on a Weibull distribution or an exponential distribution. The exponential distribution is equivalent to a Weibull distribution with a shape of 1. If you select the exponential distribution, Minitab sets the shape parameter for the distribution to 1.
