Treemap charts are an alternative method for visualizing the hierarchical structure of tree diagrams while also displaying quantities for each category. Treemap charts are particularly useful for identifying patterns in data. Tree branches are represented by rectangles, with each sub-branch represented by smaller rectangles.
Creating a simple Treemap chart
- In the Chart Builder's Chart Types section, click the
The canvas updates to display a Treemap chart template.
- Select a Columns variable from the drop-down list.Note: Click Add another column to include additional column variables.
- Lists dataset variables that are available to represent chart columns.
- Select a statistical summary function for the graphic element. The result of
the statistic determines the position of the graphic elements.There are two types of statistical summary functions. The distinction is important because it determines whether you need to specify a Value variable.
- Functions that do not require a value variable. These are functions that do not require 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. These are 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.
- 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.
- Leaf depth
- Sets the drill-down level value for the leaf nodes.
- Primary title
- The chart title.
- The chart subtitle, which displays directly beneath the chart title.
- The chart footnote, which displays beneath the chart.
