Dendrogram charts
Dendrogram charts are similar to tree charts and are typically used to illustrate a
network structure (for example, a hierarchical structure). Dendrogram charts consist of a root node
that is connected to subordinate nodes through edges or branches. The last nodes in the hierarchy
are called leaves.
Creating a simple dendrogram chart
- In the Chart Type section, click the Dendrogram
icon.
The canvas updates to display a Dendrogram chart template.
- Select at least two variables from the Field name list. You can select SELECT ALL to select all available variables. A maximum number 300 variables are recommended.
- 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.
- Click Apply to save the visualization to the project. The new visualization asset is now available on the Assets tab.
Options
- Field name
- The list provides all available variables that represent the leave nodes. You must select at least two variables.
- Show axis
- The toggle control enables or disables the display of the distance value axis.
- Linkage
- The linkage criterion determines the distance between sets of observations as a function of the pairwise distances between observations. Select Average distance, Min distance, or Max distance.
- Tree layout
-
- Left to right
- The root node displays on the left and the leaf nodes display on the right.
- Right to left
- The root node displays on the right and the leaf nodes display on the left.
- Top to bottom
- The root node displays on the top and the leaf nodes display on the bottom.
- Bottom to top
- The root node displays on the bottom and the leaf nodes display on the top.
- Radial
- The root node displays in the middle and the leaf nodes radiate from the root.
- Primary title
- The chart title.
- Subtitle
- The chart subtitle.
- Footnote
- The chart footnote.
