Problems solved by technology

As shown in FIG. 2B, the resulting expanded node 202 may cause confusion because internal nodes or items 204-208 may move around, as indicated by comparing internal nodes or items 204-206 in FIGS. 2A and 2B
[0004] Thus, a node or item arranged to display at a specific aspect ratio (such as a "vertical" aspect ratio) may look appear to be distorted and / or possibly rearrange internal features

Abstract

The invention relates to a method and a system for focus-change invariance in graphical display. The method includes computing by a processor selected items of a plurality of items in the graphical display for presentation of each item in a predetermined geometric shape. The predetermined geometric shape may include a set of predetermined coordinates in a local coordinate system in the graphical display. The plurality of items may be presented using the local coordinate system. The method may additionally include mapping the set of predetermined coordinates of a chosen item of the selected items in a [0, 0, 1, 1] coordinate system to a set of transformed coordinates for the predetermined geometric shape of the chosen item. The set of transformed coordinates allow presentation of the chosen item in the coordinate system of the graphical display. The chosen item may be displayed in the predetermined geometric shape using the set of transformed coordinates without varying the layout of the chosen item and reverting to a previously used coordinate system.

Description

technical field [0001] Aspects of the invention relate to graphical displays, interactive data visualizations, or similar presentations, such as treemap visualizations or other graphical displays, and more particularly, to methods, systems, and computer program products for implementing focus change invariance in graphical displays . Background technique [0002] Interactive data visualizations such as treemaps are gaining popularity and attention. A treemap is a display technique that allows a hierarchy of data items to be presented in a very compact form. However, tree diagrams present many ergonomic issues. For example, it can be difficult to maintain a consistent display when navigating various levels of the hierarchy (nodes focus in or focus out). Focusing (zooming in) or zooming out (zooming out) on selected nodes or parts of the treemap may result in changes to the display layout. The aspect ratio of the available display area (defined as the ratio of the width to...
