64 Interactive Control Charts Chapter 4
Control Chart Builder Options
Phase assigns phase variables. When a Phase variable is assigned, separate control limits are computed
for each phase.
Note: 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 buttons:
Undo
reverses the last change made to the window.
Start Over
returns the window to the default condition, removing all data, and clearing all zones.
Done 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.
New Y Chart 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.
Control Chart Builder Options
Control Chart Builder options appear in the red triangle menu or by right-clicking on a chart or axis.
Red Triangle Menu Options
Show Control Panel shows or hides the following elements:
– buttons
– the Select Columns box
– the drop zone borders
Show Limit Summaries shows or hides the Limit Summaries report. This report shows the control limits
(LCL and UCL) and the center line (Avg) for the chart.
Get Limits
retrieves the control limits that are stored in a data table.
Set Sample Size (appears only for Individuals charts when there is no Subgroup variable) sets a subgroup
size and quickly changes from an Individuals chart to an X-Bar chart. Missing values are taken into
account when computing limits and sigma.
Save Limits saves all parameters for the particular chart type into a new column in the existing data table.
Saved parameters include sample size, the center line, and the upper and lower control limits.
Save Summaries creates a new data table containing the sample label, sample sizes, the statistic being
plotted, the center line, and the control limits. The specific statistics included in the table depend on the
type of chart.
