The following form is used to configure Attributes Control Charts. On this form you can select the type of chart (p, np, c, or u), the method to use to calculate control limits and the centerline, axis labels, and the number of standard errors to use.
These buttons provide quick access to the following tasks.
Sets do not need to be contiguous. In other words, values with Set=1 can be followed by values with Set=2, which can be followed by values with Set=1. All values with Set=1 will then be used to generate the limits and centerlines for all values of Set=1. This will allow you to separate a middle section.
If a c chart is being generated, and the sample size is constant, a "1" can be entered here for the sample size.
