Launch Windows for Specific Control Charts

The options that you see in the launch windows vary depending on whether you are launching variable control charts or attribute control charts.

Launch Windows for Variable Control Charts

This section contains information about the launch windows for I/MR, XBar, Run, Levey Jennings, I/MR on Means, and Three Way Control Charts.

Figure 3.5 Launch Window for Variable Control Charts 

For more information about the options in the Select Columns red triangle menu, see Column Filter Menu in Using JMP.

Y

Assigns the process variables.

Subgroup

(Available only for XBar, Levey Jennings, I/MR on Means, and Three Way Control Charts.) Assigns the subgroup variables. When a subgroup variable is assigned, each point on the control chart corresponds to a summary statistic for all of the points in the subgroup.

Sample Label

(Available only for I/MR Charts.) Assigns a sample label variable to uniquely label individual measurements.

Phase

(Not available for Run Charts.) Assigns the phase variable. When a Phase variable is assigned, separate control limits are computed for each phase.

By

Identifies a variable to produce a separate analysis for each value that appears in the column.

Sort by Sample Label

Sorts all variables by the sample label.

Constant Subgroup Size

(Available only for XBar charts.) Specifies a number of observations that make up each subgroup. If the number of observations per subgroup is not constant, you should specify a column in the Subgroup role.

Note: If you specify a Subgroup variable, the platform ignores the setting for the Constant Subgroup Size option.

Dispersion Chart

(Available only for XBar charts.) Specifies the type of dispersion chart that appears below the XBar chart. You can choose between no dispersion chart, a range chart (XBar & R), or a standard deviation chart (XBar & S).

Launch Windows for Attribute Control Charts

This section contains information about the launch windows for NP, P, C, and U Control Charts.

For more information about the options in the Select Columns red triangle menu, see Column Filter Menu in Using JMP.

Y

Assigns the process variables.

Subgroup

Assigns the subgroup variables. When a subgroup variable is assigned, each point on the control chart corresponds to a summary statistic for all of the points in the subgroup.

n Trials

Assigns the subgroup sample size.

Phase

Assigns the phase variable. When a Phase variable is assigned, separate control limits are computed for each phase.

By

Identifies a variable to produce a separate analysis for each value that appears in the column.
