Printed material, information processing apparatus, and plot diagram creation method

A method of creating a plot diagram having plotted thereon a plurality of points, the plurality of points respectively corresponding to a plurality of shafts for a golf club, the method comprising the steps of:

• defining a plot region having a first axis of a first index;
• deriving values of the first index for the shafts;
• and
• plotting points, in the plot region, corresponding to the shafts at positions corresponding to the values of the first index,
• wherein the first index represents a characteristic value of a shaft and is a value that is derived using stiffness values in a plurality of positions of the shaft along a longitudinal direction of the shaft,
• wherein said method further comprises the step of printing a plurality of sub-regions on the plot region in such a mode that the plurality of sub-regions are distinguishable from each other by a user, the plurality of sub-regions respectively corresponding to different types of golfer, and
• wherein at least one point of the plurality of points is positioned inside of one of the plurality of sub-regions and at least another one point of the plurality of points is positioned inside of another of plurality of the sub-regions.
