SPC Chart default settings

You can change the default settings for SPC charts in the GainSeeker System Administration module. Customizing these options to meet your organization's needs can make routine analysis and charting activities faster and more convenient.

Most of these options can also be temporarily changed for a chart using the Settings tab when a chart is first drawn or when it is open.

Settings tab settings are temporary in that each time the GainSeeker Charts module is closed, the settings revert back to the default settings established in the GainSeeker System Administration module .

Chart skin (SPC) =

Use this setting to apply a chart skin to charts drawn for SPC retrievals. The default chart skin can be temporarily overridden by users from the Settings tab.

Chart skins included with GainSeeker are added to each configuration when the System Administration module is initially loaded and to any new configurations you might add.

You can also create and name your own skins, which can have practical advantages on decision-making based on data when analysts see data displayed the same way. For more information, See Chart Skins
