Abstract
Methods and apparatus to display and scroll hierarchical data. A plurality of parent nodes can be displayed within a first display area, with each displayed parent node of the plurality of parent nodes having at least one child node. A computer can determine that at most one child node for each displayed parent node of the plurality of parent nodes is to be displayed. A child node scrolling instruction can be received. A child node display percentile can be determined based at least in part on the child node scrolling instruction. One child node of each displayed parent node of the plurality of parent nodes can be selected based at least in part on the determined child node display percentile. Each selected one child node of each displayed parent node of the plurality of parent nodes can be displayed in a second display area, with each displayed child node being displayed as associated with the displayed parent node of the displayed child node.
