Abstract
A shovel includes a cabin in which a display monitor is provided, a main pump that generates a hydraulic pressure, an internal combustion engine that drives the main pump, and a display control part configured to generate display information to be displayed on the display monitor based on information communicated between the display control part and the internal combustion engine, and cause the generated display information to be displayed on the display monitor. The display control part is configured to cause the fuel efficiency of the internal combustion engine to be displayed simultaneously in multiple graphs having different time axes on a single display screen. The graphs show the fuel efficiency of the internal combustion engine over time.
