A method and apparatus for positioning labels (25) on a graphical display (2 ), which, in an illustrative embodiment, can include labels (25) for aircraft icons (20) in an air traffic control system's computer graphics display. The present invention advantageously identifies clusters of overlapping labels a nd objects (6, 8, 10, 18), and calculates non-overlapping label positions on a cluster by cluster basis. In another aspect of the present invention, the movement of labels (25) is accomplished in a smooth, incremental fashion so that cognitive distraction to the user of the graphical display terminal is kept to a minimum.
