Figure display device, figure display method and storage medium storing a figure display program

摘要

A figure display device, a figure display method and a storage medium having a figure display program are described. According to one implementation, a figure display device includes a figure display section; an assumed equation input section; and a figure assumed portion discrimination display control section. The figure display section displays a figure. The assumed equation input section is used to input an assumed equation of the figure according to user operation. The figure assumed portion discrimination display control section deforms a corresponding portion of the assumed equation in the figure to match a figure portion obtained by the assumed equation, and illustrates a content represented by the assumed equation in the figure displayed with discrimination.

主权项

1. A figure display device comprising:
a display; and a processor which is configured to:
display a figure on the display;input an equation regarding the figure according to a user operation;detect a portion in the figure corresponding to the input equation; anddisplay with discrimination in the displayed figure, content represented by the input equation, wherein the input equation is a ratio equation corresponding to the portion in the figure; and wherein the processor is further configured to:
detect the portion in the figure corresponding to the ratio equation;display content represented by the ratio equation in the detected corresponding portion in the figure;judge whether or not an identifier in the entered equation is defined in the displayed figure;when it is judged that the identifier in the entered equation is defined in the displayed figure, judge whether or not an order of a sign of the identifier is in reverse;when it is judged that the order of the sign of the identifier is in reverse, display an error message and a query message regarding whether or not to correct the order; andcorrect the order of the sign of the identifier based on a user operation requesting that the order be corrected.
