Manipulating Displays
Manipulating Displays
Reports in JMP are built in a hierarchical manner by nesting and gluing together different types of
rectangular boxes. To manipulate reports with scripts, you first need to learn a bit about how these boxes
work. You might want to learn more about how this works if:
• You want to manipulate display boxes from existing reports.
This section introduces JMP reports in general and then discusses how to navigate reports, extract data
from them, and change them from JSL.
• You want to construct your own reports.
See the next section, “Constructing Display Trees” on page 345, after first reviewing the introduction
that begins this section.
As you work with displays, a preference might be of use. In the General category of Preferences, select
Report Invalid Display Box Messages to see possible errors. The default value is off.
When this preference is off and a script contains invalid display box messages, JMP ignores those errors and
continues executing the script. When this preference is on, script execution stops when an invalid display
box is reached, and an error is sent to the log.
Using this preference while you are developing your script helps you avoid possible problems.
Introduction to Display Boxes
Here are a few diagrams of the most common types of display boxes in JMP.

VListBoxes glue boxes together vertically.
HListBoxes glue boxes together horizontally.
