A method of dynamic representation using a support, a removable reference sheet secured to the support and bearing at least two inscribed parameters or variables, movable members for mounting on the sheet by detachable magnetic attachment with the support, and a photo-copying apparatus. The members can be mounted on the sheet in a succession of different positions according to pairs of variables. The support is turned upside down after each positioning of the members and photocopied in order to obtain a succession of instantaneous representations of parts of a dynamic process. |
