Abstract: In a display system in an excavator, a position of an upper boundary line and a position of a lower boundary line are calculated. The upper boundary line indicates a height of a top of a cross section of a display object surface. The lower boundary line indicates a height of a bottom of the cross section of the display object surface. A predetermined reference point of a display range is set based on a positional relationship in an up-and-down direction between the current position of the excavator and the upper boundary line or between the current position of the excavator and the lower boundary line. A guidance picture showing a cross section of the display object surface included in the predetermined display range as seen from a side of the excavator, and the current position of the excavator, is displayed.
