PURPOSE: To improve both a general-purpose property and a value added, by printing collectively graph statical information as well as graph information.

CONSTITUTION: The constitution ratio as well as each data are printed automatically and collectively and deliveres as shown by (3) and (4) in case the constitution ratio of each data is chiefly graphed in response to the type of the graph to be produced for the printing type of data which are collectively printed. For others, the list of data suited to the character of the graph related to each data and a collective print are delivered as shown by (1) and (2). Therefore if a mean value must be drawn, a symbol showing the mean value is used to connect the mean value symbols the (a) and (a') and the (b) and (b') at the left and right ends of the graph. Thus the mean value can be easily drawn.
