P charts: fixed sample size? varying sample size? both?

X-bar and R: 2-9 subgroups? 2-7? 2-5?

X-bar and S: >7, >9, >10 subgroups?

etc.

Is there a EC-vetted decision chart that captures all or most of the control charts and is more accurate especially with respect to subgroup information: X-bar, Xbar-sub-d, R, r-sub-d, X-bar&R, IX, IX-sub-d, S, MR, I&MR, CUSUM, EWMA, MACC, g charts, run chart, trend chart, etc.?

Thanks for your help!

Regards,
