The Process Screening red triangle menu contains options to customize the display and to save calculated statistics. The options that operate on selected items are also accessible by right-clicking the Column column in the Summary table.
Adds columns for Largest Upshift and Upshift Position to the Summary table. The largest upward shift in the series that exceeds one within-sigma unit is identified. See Shift Magnitudes and Positions.
Adds columns for Largest Downshift and Downshift Position to the Summary table. The largest downward shift in the series that exceeds one within-sigma unit is identified. See Shift Magnitudes and Positions.
Note: The Shift Graph does not show the positions of Largest Upshift and Largest Downshift values that appear in the Summary table if the shifts are less than the specified Shift Threshold number of within-sigma units in magnitude. See Additional Example of Process Screening.
(Available only when specification limits are defined.) The Goal Plot shows, for each variable, the spec-normalized mean shift on the X axis, and the spec-normalized standard deviation on the Y axis. It is useful for getting a quick, summary view of how the variables are conforming to specification limits. See Goal Plot in the Quality and Process Methods book for more information about goal plots and their features.
Shows or hides the Ppk level shading. This is turned on by default. The shaded areas are described as follows, with p representing the value shown in the box beneath Ppk. By default, p = 1.33.
