Properties Associated with Control Charts and Capability
The Specification Limits, Control Limits, Sigma, and Process Capability Distribution properties are associated with control charts and capability.
Spec Limits
Specification limits are used when you perform a capability analysis using the Distribution and Capability platforms.
You can specify any combination of a Lower Spec Limit, an Upper Spec Limit, or a Target. The
Show as graph reference lines
option displays the specification limits and target that you specify as reference lines on appropriate plots.
Control Limits
The Control Limits column property enables you to specify control limits for a column, rather that having JMP calculate control limits from the values in the column. This is useful when you are comparing process data to historical control limits.
The Control Limits column property can be assigned only to a numeric column. To assign the Control Limits column property, select the control chart type and then enter the requested values. If any of these entries are missing, JMP replaces it with a calculated value in the control chart.
Sigma
Use the Sigma property to enter a known sigma value. This value is used by applications such as control charts or any application that requires a sigma value to complete computations. If no sigma value is supplied, sigma is calculated from the sample.
Process Capability Distribution
The Process Capability Distribution column property specifies a process distribution for the column. The Process Capability Distribution column property is used only in the Process Capability platform. See also
