XBar
Properties
| Average | Gets the average subgroup standard deviation (S̄) computed during phase-I analysis, which serves as the center line of the Standard Deviations series. |
| Grand | Gets the grand mean (X̄̄) — the average of all subgroup means — computed during phase-I analysis. |
| Means | Gets the Means series. Contains the subgroup means and the computed XBar control limits. |
| Standard | Gets the Standard Deviations series. Contains the subgroup sample standard deviations and the computed S-chart control limits. |
| State |
Gets the current lifecycle state of this chart.
(Inherited from ControlChart) |
| Subgroup | Gets the subgroup size (number of measurements per subgroup). All subgroups must have the same size; the equal size is validated during Analyze(). |
