Standard overrides settings for SPC charts

If you want to analyze data as if its standards were configured differently—without actually changing those standards—you can expand the Standard overrides tree and change the settings.

Information about each of these settings is featured in this topic.

You can assign default settings to charts in the GainSeeker System Administration module. See Chart Defaults settings
