Abstract

An electronic apparatus includes a memory, a display, and a processor. The processor obtains an instruction on a figure-related process. If a type of a figure indicated by the instruction is a type unable to be drawn with function data stored in the memory, the processor: sends relevant data to at least one server; receives, from the server, drawing data generated by the server executing, based on the relevant data, an arithmetic operation required for the figure-related process; and performs the process on the display in accordance with the drawing data. If the type is a type able to be drawn with the function data, the processor executes an arithmetic operation required for the figure-related process using the function data without requesting the server to execute the arithmetic operation, and performs the process on the display in accordance with drawing data generated as a result of the arithmetic operation.
