Method and apparatus for data alteration by manipulation of representational graphs

(57) The method and equipment for changing data by operation of a summary display dynamic graph are offered. The method and equipment for using a dynamic graph especially are given, The computer user can operate graphical form directly and this changes here the digital display to which the data it not only changes a graph, but given to a computer user relates, and the data which corresponds and serves as the foundation and which were tabulated. A method and equipment A processing unit, a system memory, and user operation equipment, Since it is used with the computer system which has a video display, it is provided, and the dynamic graph which has whether the focus is connected here and one which is not connected of those at least one data display elements is generated. Generation of a dynamic graph generates and saves the graphics and statistical characteristics of a dynamic graph. Operation of the data display element by user operation equipment may also contain the step which reconstructs a dynamic graph in order to choose the data display element which connected the focus for which operation asks. Change of the dynamic graph according to user operation includes change of the graph data used as the foundation not only corresponding to a graphic display but a dynamic graph. By it, a user changes data by intuitive operation of a display dynamic graph, and this method and equipment offer the easy and easy method of changing the correlation between related data.
