The method involves receiving input signals on or at a computer user station to change a size of the graphic representation by zooming a predefined display region on a user interface (1) or selecting an object field (2) of the graphic representation. The object field is fixed on the user interface in a size sufficient for display or user interaction, even if a size change of the graphic representation into a range is unsuitable for the display or for the user interaction occurs due to zooming, through object filed selection.
