Krishaar,

What I see is that using plug gages in attributes is one of the following:
NP and C charts are used for constants with change.
P and U charts are for defects or with defects that varies.

Pick the one that best suits you. Remember when you perform your gage R&R
what is the precent you will allow to be rejected.
