The standard set of FastReport Business Graphics includes two classes providing data presentation for hierarchical charts.
The Children field builds hierarchical interrelations between the records. You may indicate which data elements should be used as tags for elements, values, or child records.
You may build a hierarchical structure based on table sources. A collection with the names of fields and the order of nesting can be set. Additionally, you may set the limit of dipping by hierarchy.
Some charts, like Sunburst, may display the root element.
