Chapter 4 Interactive Control Charts 65
Control Chart Builder Options
Include Missing Categories enable the graph to collect rows with missing values in a categorical
column, and display the missing values on the graph as a separate category. This option is not available
for continuous X-variables since there is no location on the X-axis to display the collected missing
values.
Script
contains options that are available to all platforms. See Using JMP.
Right-Click Chart Options
The following options appear when you right-click on a chart:
Points provides the following options:
– Statistic changes the statistic plotted on the chart. See “Additional Example of Control Chart
Builder” on page 67.
– Individual Points show or hide individual observations in a subgroup. This option appears only if a
Subgroup variable is specified.
– Show Points hides or shows the points on the chart.
Limits provides the following options:
– Sigma specifies the method of computing sigma. See “Sigma” on page 66.
– Zones shows or hides the zones on the chart. The zones are defined as one, two, and three sigmas on
either side of the mean.
– Spec Limits shows or hides the specification limits on the chart. This option appears only for charts
showing individual points or averages.
– Add Limits specifies custom control limits to be plotted on the chart.
– Show Limits hides or shows the control limits on the chart.
– Show Center Line hides or shows the center line on the chart.
Connecting Line provides the following option:
– Show Connect Line shows connecting lines between the points.
Add Dispersion Chart adds a dispersion chart to the chart area. Change the chart type with the Points
options. A dispersion chart illustrates the variation in the data by plotting one of many forms of
dispersion, including the range, standard deviation, or moving range.
Set Sample Size (appears only for Individuals charts when there is no Subgroup variable) sets a subgroup
size and quickly change from an Individuals chart to an X-Bar chart. Missing values are taken into
account when computing limits and sigma.
Warnings provides the following options:
– Customize Tests lets you design custom tests. After the option is selected, the Customize Tests
window appears for designing the tests.
– Tests let you select which statistical control tests to enable.
Note: Move your cursor over a flagged point on the chart to see a description of the test that failed.
