Branch label
Overview
Branch label styles provide different ways to highlight and group the tree leaf branches.The annotation properties can be provided in two formats:
- !groups_class Provides the annotation details for a specified group name or id.
- Leaf/Branch based annotation details can provided for each leaf along with leaf Name.
Here is an quick example
Please consult our examples trees 'Branch Label style 1', 'Branch Label style 2' in the DEMOS project.
