    摘要: A display apparatus includes circuitry to receive an input of a plurality of strokes representing a drawing that includes one or more drawing components including a first drawing component. The plurality of strokes is divided under a predetermined condition to obtain the one or more drawing components. The circuitry stores, in a memory, each of the one or more drawing components and drawing data representing the drawing. The circuitry displays, on a display screen, in response to receiving an input of a second drawing component, the drawing represented by the drawing data based on the first drawing component and the second drawing component.
