An input section (3) allows a user to input an input signal including selection information and operational direction information. A dimensional constraint data storing section (4) stores dimensional constraint data of a graphic object. An extent data storing section stores extent data of the graphic object. An arithmetic section (5) determines a moving direction of a selected graphic object on the basis of the dimensional constraint data and data of an initial moving direction. The selected graphic object is detected on the basis of the selection information. The initial moving direction is detected on the basis of the operational direction information. The arithmetic section generates data representing arrangement of a scale along the moving direction of the selected graphic object.
