PURPOSE:To display more information at the same time by additionally displaying three more pieces of information with the lengths of the respective sides of a cube displayed in a three-dimensional space. CONSTITUTION:A display position in the direction of a time base is defined by using plural pieces of information among the start period, end period, and operation period of an operation item. Further, a display position based upon information defined with two axes perpendicular to the time base is defined by setting the position of the center axis in the time base direction of the cube showing the operation item at a corresponding position on a matrix defined by the division of the respective axes. Then the lengths of the sizes of the cube in the two axial directions except the time base direction are defined according to the mandays of the operation item, and optional one piece of information that a user specifies between the difficulty of the operation and a physical quantity used for the operation by using an input/output interface, i.e., two pieces of information in total. The respective pieces of information have quantitative values, and the lengths of the sizes are set to proportional lengths according to the respective values. |
