Handling a Dendrogram
A dendrogram illustrates the environment of an object. You can improve its display:
• in the report parameters:
• modify its Display mode (circular or horizontal)
• modify the Number of displayed levels by default
• in the dendrogram:
• display an additional level for a single branch
• modify the depth of display of a branch levels from a specific object
You can also:
• display a dendrogram in full page
• zoom in and move through the dendrogram
Example of a Report Template showing a dendrogram:
“Environment report”
With Display and Number of displayed levels parameters, this Report Template also includes the following parameters:
Subject: defines the source object of the dendrogram.
Hierarchy: defines the link (via a MetaAssociationEnd or a query) browsed recursively to display the objects.
Deepness: defines the number of displayable levels of a branch.
Improving a dendrogram readability 
To improve a dendrogram readability:
1. (If needed) Zoom in and move through dendrogram.
2. Edit the report (click More > Edit Report ).
3. In the edit pane, Styles section, modify the style parameters, then click Apply.
Select, for example:
• the most suitable Display mode
Circular
Horizontal
• the default Number of displayed levels for all of the branches
E.g.: 2 levels displayed by default
4. Click an object:
• at the end of a branch to display an additional level (objects with bold names have additional levels)
• within a branch to hide the deeper levels
Displaying the dendrogram in full page

*To exit the full page mode, click Exit full page mode .
Zooming in and moving through a dendrogram

*To return to the original size, at the top right corner of the graphic, click Reset Zoom .
The zoom is performed on the dendrogram as a whole.
