SPC Chart - Chart Options 1

Use this tab to define the following parameters:

Element Name Description
Show process specifications Select this checkbox to define whether to display the default specification limit lines (as computed by the analysis) on the chart only when the Specification Limits tab> Specification Limits dropdown list is set to None. Otherwise, the specification limits in that option will override this selection.
Note:

• If None option is selected, the analysis will not generate any specification limits on the chart.

• If Use LSL, Nominal and USL option is selected, the analysis will look for variables named *_LSL, *_NOM and *_USL for each characteristic (where '*' is the name of the characteristic) and use the values in the respective variables as the Lower Specification Limit, Nominal and Upper Specification Limit.

• Each time the value in the *_LSL or *_NOM or *_USL variable changes moving downward in the column, the system will create a new set on the chart.

• If a value in the *_LSL or *_NOM or *_USL variable is blank, the system will use the previous valid value found in the respective column.
