Tree charts
Tree charts represent hierarchy in a tree-like structure. The structure of a Tree chart
consists of a root node (has no parent node), line connections (named branches), and leaf nodes
(have no child nodes). Line connections represent the relationships and connections between the
members.
Creating a simple tree chart
- In the Chart Type section, click the Tree
icon.
The canvas updates to display a Tree chart template.
- Select a Columns variable from the drop-down list.Note: Click Add another column to include more column variables.
- Click the Save visualization in the project control. Select Create a new asset or Append to existing asset. Provide a Visualization asset name, an optional description, and a chart name.

Options
- Columns
- Lists variables that are available to represent chart columns.
- Summary
- Select a statistical summary function for the graphic element. The result of
the statistic determines the position of the graphic elements.Two types of statistical summary functions are available. The distinction is important because it determines whether you need to specify a Value variable.
- Functions that do not require a value variable
- All count and percentage statistics are in this category. These statistics are available when there is no defined Value variable.
- Functions that do require a value variable
- For example, the Mean function requires a variable on which the mean is calculated. These statistics are available when there is a defined Value variable.
- Value
- This field displays when a Summary function that requires a value variable, is selected. Select a variable to serve as the basis for the summary value.
