Graph display device, graph display method and computer-readable medium recording control program
First Claim
1. A graph display device comprising:
- a display;
an input device with a specified key;
a processor; and
a memory storing instructions that, when executed by the processor, control the processor to perform operations comprising;
accepting an input of one of a first functional expression that includes a first term that contains a variable multiplied by a first coefficient that is inputted as a non-numerical character, and a second functional expression that includes a second term that contains a variable multiplied by a second coefficient that is inputted as a number;
in response to accepting the input of the first functional expression, and without an input of a specified operation to the specified key of the input device, displaying on the display (i) the inputted first functional expression, (ii) a first graph corresponding to the inputted first functional expression, and (iii) a first user interface object corresponding to the first coefficient, wherein the first graph is redrawn in accordance with a change in a position designated by a user operation with respect to the first user interface object;
in response to accepting the input of the second functional expression, displaying on the display the inputted second functional expression and a second graph corresponding to the inputted second functional expression without displaying a user interface object corresponding to the second coefficient; and
while the second functional expression and the second graph are displayed on the display, in response to accepting the specified operation to the specified key of the input device, highlighting the second coefficient and displaying on the display a second user interface object corresponding to the highlighted second coefficient, wherein the second graph is redrawn in accordance with a change in a position designated by a user operation with respect to the second user interface object.

Abstract
A graph display device includes an expression input unit, a graph display control unit, first and second display control units and a coefficient changed graph display control unit. The expression input unit recognizes a functional expression. The graph display control unit displays a graph corresponding to the recognized functional expression in a display part. The first display control unit displays a first user interface object for changing a numeric value set to a variable when a coefficient in the functional expression is the variable. The second display control unit displays a second user interface object for changing a numeric value as a constant when a coefficient in the functional expression is the constant. The coefficient changed graph display control unit displays a graph corresponding to the functional expression in which a numeric value changed by the first or second user interface object is set as a coefficient value.
