A multi-dimensional data set assigns data values to positions in a multi-dimensional geometrical space. A visualization is derived from the multi-dimensional data set, for example, by way of a volume or surface rendering technique. The visualization is reproduced on a display and parts that have been missed in the display are detected and indicated. For example, a new representation is made on the basis of the detected missed parts, for example, from another point of view and/or another field of view.
