Users want to retrieve parts of the data stored and to have them shown in graphical form. They need an easy and flexible query language to select the data needed and to describe the form of representation. The existing query languages do not suit this purpose without amendments. This paper presents a proposal for adaptation and gives some examples for query formulation. Moreover, it discusses the special problems of graphical input and output.
