Abstract
Abstract Disclosed hereinbelow is an automatic graphic printer which is characterized in that; it automatically sets the scale information of the graphic axes as a function of the sample data value, and therefore, even if designation of an information related to complex scales is deleted, such a scale information based on the sample data can be automatically set, and as a result, any of the conventional graphs can be drawn within a shorter period of time than before by using simplified designation means. In addition, plotting position of the sample data can be set in any suitable position on the graph so that an optimum scale can easily be provided.
