H-tree Pedigree View - example showing 5 generations(31 people total)

H-Tree Pedigree view is an interactive Charts Charts category view addon that presents a navigable ancestors tree using the current active person as a starting point. Clicking another person in the family tree will make that person the active person and will redraw the family tree based on them.

The H-Tree is a structured, space-efficient technique for pedigree visualization (to display ancestral trees).

The H-tree based layout can be used to display ancestral trees. This layout increases the number of displayable generations, via a symmetrically arranged structure, provides the the user with an overview that allows them to understand and navigate through the data.



From the   Charts category view select the H-Tree Pedigree View icon or select View > H-Tree Pedigree View from the menu.
