Attribute Charts Results - Parts Tab

Control Charts for Variables vs. Charts for Attributes

Select the Parts tab of the Results dialog box to access the options described here. Note that this tab is only available when creating Short Run charts for multiple parts.

Raw Chart (no part)

 Select this option button to produce a raw chart with no part information (without subtracting nominal values for parts, or standardization within part).

Nominal Chart

Select this option button to produce a nominal or target short run chart. For nominal or target short run charts, the data within parts are transformed by subtracting the respective part means or a different constant value specified by clicking on the Nominal/target button (see below).  

Specifications for transforming values

Nominal/Target

Click this button to display the Specify nominal/target values for parts dialog box in which you can specify target values.

Sigma (R/S)

Descriptive stats/specs for the parts
