You can drag other variables into the various zones to augment the analysis and use the Control Chart Builder Options to further examine the data. Some of the right-click chart options (for example, show or hide points, limits, warnings, and zones; select statistic and sigma options) also appear on the left hand side of the chart for easy access.
Each point plotted on the chart represents an individual process measurement or summary statistic. Subgroups should be chosen rationally, that is, they should be chosen to maximize the probability of seeing a true process signal between subgroups.
