Working with Treemaps
About Treemaps
A treemap displays a hierarchy or a category as a set of rectangular tiles. Each tile represents a category value or a hierarchy node. The size of each tile represents either the frequency count or the value of a measure. If you assign a measure to the Color role, then the color
of each tile represents the value of that measure.
Data Roles for a Treemap
The basic data roles
for a treemap are:
Tile
specifies categories
or a hierarchy that are used to create the tiles in the treemap. If
you specify categories for the Tile role,
the order of the categories determines the level of each category.
Drag and drop the categories to place them in the order that you want.
Size
specifies a measure that determines the size of each tile. If you do not specify the
Size role, then the tile size is determined by the frequency count.
Note: If any of the aggregated
values for the Size role results in a negative
size value or a value of zero, then an error appears.
Color
specifies a measure
that determines the color of the tiles.
Specify Properties for a Treemap
On the Properties tab,
you can specify the following options:
Name
specifies the name of the visualization.
Title
specifies the title
that appears above the graph.
Generate graph title
specifies that the graph title is generated automatically based on the data items
in the visualization.
Show data labels
shows a text label for each tile in the treemap.
Frequency
specifies whether the
frequency values are displayed as the number of values (Count)
or as the percentage of values (Percent).
Arrangement
specifies the layout
of the tiles in the treemap. Select one of the following values:
Standard
arranges the tiles
into squares, with the largest tiles generally at the bottom left.
Flow
arranges the tiles from largest to smallest, with the largest tile at the top left.
Toggle
arranges the tiles into a single row or column, with the largest tile on the left
or at the top.
The orientation of the tiles alternates between hierarchy levels. The top level is arranged as a
row, the second level is a column, and so on.
specifies the number
of levels that are displayed beneath the current level.
selects the gradient colors for the visualization.
You can click 
to select the values that are used to assign the
colors. See Specify a Custom Data Range.
to select the values that are used to assign the
colors. See Specify a Custom Data Range.Create a Hierarchy from a Treemap
If your treemap contains
categories in the Tile role, then you can
create a new hierarchy by using the categories.
On the Roles tab, click on the drop-down list for the Tile role,
and then select Create Hierarchy. A new hierarchy
is created with the name of the first category in the hierarchy.
