A gage run chart is a plot of all of your observations by operator and part number. A horizontal reference line is drawn at the mean, which can be calculated from the data, or a value you enter from prior knowledge of the process. You can use this chart to quickly assess differences in measurements between different operators and parts. A stable process would give you a random horizontal scattering of points; an operator or part effect would give you some kind of pattern in the plot.
Part numbers: Enter the column containing part names or numbers.
Operators: Enter the column containing operator names or numbers.
Measurement data: Enter the column containing the observed measurements.
Trial numbers: Enter the column containing trial numbers (optional).
Historical mean: Enter your own value for the horizontal reference line. By default, the reference line is the mean of all observations (optional).
