Two sequences of data sets having at least two dimensions and referring to an object which changes over time are specified to a computer. Each data set in each sequence is assigned a measure of time which can be used to determine the temporal relationship of the data sets to the other data sets in the respective sequence. The computer compares the first data set) in the first sequence with the data sets in the second sequence and automatically determines a first data set from the second sequence corresponding to a first data set from the first sequence. With the aid of the corresponding first data sets in the first and second sequences and the measures of time assigned to the data sets, the computer then determines, for each of the other data sets in the first sequence, the corresponding data set from the second sequence.
