Abstract

A multi-ownership tree-map visualization system can include a tree-map configured to visualize a set of interrelated nodes in which at least one individual node in the set is related to at least two parent nodes in the set. The system further can include an event handler programmed to process a proximity event associated with a specific portion of the tree-map by highlighting multiple portions of the tree-map in which the portions represent a single node in the set. In this regard, the proximity event can include a mouse-over event, a mouse-click event, or a keyboard selection event, to name a few. The system yet further can include logic for displaying a call-out box for each portion of the tree-map associated with the single node in the set.

Claims

1. A method for presenting multi-ownership in a tree-map, the method comprising the steps of:

detecting a proximity event about a representation for a node in the tree-map;

determining through said representation a unique identifier for said node;

locating all other representations in the tree-map which corresponding to said unique identifier; and

,

highlighting each of said representations in the tree-map.

2. The method of claim 1, wherein said step of highlighting comprises displaying a call-out box for each of said representations.

3. The method of claim 1, wherein said detecting step comprises the step of receiving a mouse-over event in an event handler for the tree-map.

4. The method of claim 1, wherein said detecting step comprises the step of receiving a mouse-over event in an event handler for said representation about which said proximity event is detected.

5. The method of claim 1, wherein said detecting step comprises the step of receiving a mouse-click event in an event handler for the tree-map.

6. The method of claim 1, wherein said detecting step comprises the step of receiving a mouse-click event in an event handler for said representation about which said proximity event is detected.
