STATGRAPHICS: Process Capability Analysis (Individuals)

Good morning,

i'm working with data following a normal distribution and my purpose is to estimate the capability of my method by measuring Cp and Cpk values with the process capability analysis. The result show me informations about long-term capability with its own sigma value and Ppk result, and short-term capability with another sigma value and Cpk result. The graphic output is relative to the long-term capability; how can i obtain the short-term output? May someone help?

Thanks for helping me.
