Abstract: A graph display apparatus includes a display unit and a processor. The display unit includes a touch panel. The processor performs the following processes: controlling the display unit to display a graph on a graph display area in a coordinate range, the graph corresponding to an expression; acquiring a position designated by a touch of a user on the graph display area; and when a drag operation is detected after the touch of the user ends, changing the coordinate range with the designated position fixed in response to the drag operation, thereby reducing or enlarging the graph, and controlling the display unit to display the reduced or enlarged graph.

Abstract: A graph display apparatus includes a display unit and a processor. The display unit includes a display screen. The processor performs following processes of: determining an expression as a graph display object according to positions on the display screen, the positions being designated by a user; generating an operation receiver for changing a numerical value of a coefficient included in the determined expression, according to an operation of the user; displaying the graph of the determined expression and the generated operation receiver on the display screen; and changing the graph displayed on the display screen, according to the operation of the user on the displayed operation receiver.

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.

Abstract: A formula display control device includes a display unit, a text display control unit, a formula designation unit, a template formula generation unit and a template formula display control unit. The text display control unit displays text including a formula on the display unit. The formula designation unit designates the formula in the text displayed on the display unit in response to a user operation. The template formula generation unit replaces a coefficient portion in the formula with an input frame to generate a template formula when a coefficient is included in the designated formula. The template formula display control unit displays the template formula generated by the template formula generation unit as text which is displayed on the display unit.
