In the SPC data for a sample, is there a way I can reference and/or modify the “Range”, “Xbar” Sum", “Standard Deviation”, etc. values? I know these are automatically calculated by the SPC module, but if I’d like to reference them or inject my own values to those properties, how can I reference them in scripting?
