The 11ea262f_f38c_06d8_a3cc_29f1e0ab3dfd_TB3615_11-chart, or X-bar chart, is used to monitor the centering of the process by plotting the sample means over time. It is the best choice because it tracks the average performance of the process, indicating whether the process is centered on the target value or not. The R-chart, p-chart, and np-chart are used to monitor the variability, proportion, and count of nonconformities respectively, and do not provide information about centering.
