Determines the size of the rectangles based on the values of the specified
variable. See “Sizes” on page 469.
(Required) Specifies the category that comprises the tree map. See
“Categories” on page 470.
Changes the ordering from alphabetical (where values progress from the top
left to the lower right) to order by the specified variable. You can specify
more than one ordering variable. See “Ordering” on page 470.
Colors the rectangles corresponding to the levels of the specified variable.
• If the variable is continuous, the colors are based on a continuous color
spectrum.
• If the variable is categorical, the default colors are selected in order from
JMPs color theme.
See “Coloring” on page 470.
Identifies a column that creates a report consisting of separate tree maps for
each level of the variable.
For more information about the launch window, see Using JMP.
Sizes
If you want the size of the rectangles to correspond to the levels of a variable, specify a Sizes variable. The
rectangle size is proportional to the sum of the Sizes variable across all of the rows corresponding to a
category. If you do not specify a Sizes variable, the rectangle size is proportional to the number of rows for
each category.
