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. |
