3-sigma x-chart in excel

Not in terms of “how many sigmas”. You set the original limits to be ±3 sigma, then your process improves and the process sigma is reduced, then now the control limits are at more than ±3 sigma, so you change them to be ±3 sigma again. “The +/- sigma limits on the chart should be somewhat of a reflection of your process Sigma Level.
