Hierarchy Child Algorithm

This content is outdated and is no longer being maintained. It is provided as a courtesy for individuals who are still using these technologies. This page may contain URLs that were valid when originally published, but now link to sites or pages that no longer exist.

The hierarchy child (hierChild) algorithm works with the hierarchy root (hierRoot) algorithm to create hierarchical tree layouts. The hierarchy child algorithm aligns and positions its child layout nodes in a linear path under the hierRoot layout node.

Parameters

Parameter	Values	Description
linDir	fromL (from left, default) fromR (from right) fromT (from top) fromB (from bottom)	Specifies whether child nodes are arranged from left to right, right to left, top to bottom, or bottom to top.
chAlign	t (top) b (bottom) l (left, default) r (right)	Specifies the alignment of child nodes.
secLinDir	none (default) fromL (from left) fromR (from right) fromT (from top) fromB (from bottom)	Specifies whether secondary child nodes are arranged from left to right, right to left, top to bottom, or bottom to top.
secChAlign	none (default) t (top) b (bottom) l (left, default) r (right)	Specifies the alignment of secondary child nodes.
horzAlign	l (left) ctr (center, default) r (right)	Aligns all the child nodes in the space reserved for the parent node, and adjusts child node positions along the x-axis.
vertAlign	t (top) mid (middle, default) b (bottom)	Aligns all the child nodes in the space reserved for the parent node, and adjusts child node positions along the y-axis.

Constraints

Constraint	Default value	Description
w	100	Specifies the width of the bounding box for a node.
h	100	Specifies the height of the bounding box for a node.
sibSp	0	Specifies the distance between child nodes.
secSibSp	0	Specifies the distance between secondary child nodes.
