Launch the Control Chart Builder by selecting Analyze > Quality and Process > Control Chart Builder.
To begin creating a control chart, drag variables from the Select Columns box into the zones. If you drop variables in the center, JMP guesses where to put them based on whether the variables are continuous or categorical. The Control Chart Builder contains the following zones:
Assigns subgroup variables. To define subgroup levels as a combination of multiple columns, add multiple variables to the Subgroup zone. 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.
Assigns phase variables. When a Phase variable is assigned, separate control limits are computed for each phase. See also
Populates the window with the last analysis that you performed. The Recall button becomes the Undo button once you perform an action.
Hides the buttons and the Select Columns box and removes all drop zone outlines. In this presentation-friendly format, you can copy the graph to other programs. To restore the window to the interactive mode, click Show Control Panel on the Control Chart Builder red triangle menu.
Allows you to select Shewhart Variables, Shewhart Attribute, or Rare Event control chart types. If you select an Attribute chart type, an n Trials box and zone appear on the chart.
Assigns a lot size when an attribute control chart is selected. Appears if you select an Attribute chart type.
Produces a copy of the current chart for every column selected in the Select Columns box. The new charts use the selected columns in the Y role.
Once you drag variables to the chart, other buttons and options appear at the left bottom of the screen that enable you to show, hide or switch items on the chart (See Control Chart Builder Window). Many of these functions (Points, Limits, Warnings) are the same as the functions available when you right-click the chart. For more information, refer to . For information about warnings and rules, see and .
Enables you to produce a three-way chart for variable chart types. The subgroup size must be greater than one. The plotting statistic is based on subgroup averages, within-subgroup variation, or between-subgroup variation. The default set of three includes a presummarized chart of the averages using Moving Range limits, a Moving Range chart and a Range chart.
Allows the chart to respond in real time to selection changes. There are several standard groups of responses that are recognized and pre-scored (for example, pass/fail, yes/no, Likert Scales, conforming/non-conforming, and defective/non-defective). If you are analyzing results from a survey and want to focus solely on a specific sector of the results for one or more questions, you can make the selection on the screen and the chart rescores and replots the chart immediately. The Event Chooser is available for attribute charts with response columns that have a modeling type of nominal or ordinal. The Event Chooser does not appear for response columns with a modeling type of continuous.
