Abstract

A graph display control device includes a formula display control unit, a graph display control unit and an operation-display-element display control unit. The formula display control unit displays a plurality of function formulas containing parameters on a display unit. The graph display control unit displays a graph image corresponding to one of the plurality of function formulas displayed by the formula display control unit, on the display unit so as to be discriminable according to the plurality of function formulas. The operation-display-element display control unit discriminately displays an operation display element for designating a numerical value of a parameter contained in at least one of the plurality of function formulas, on the display unit in correspondence to the graph images respectively displayed discriminately in relation to the function formulas by the graph display control unit.
