Evaluation display system, method, and computer-readable storage medium

An evaluation display method comprising:

• displaying a current position of a vehicle and a map around the current position on a display unit;
• acquiring a current evaluation indicating a fuel efficiency evaluation of each unit interval in a current travel of the vehicle;
• acquiring a past evaluation indicating a fuel efficiency evaluation of the each unit interval in a past travel that is earlier than the current travel;
• displaying the current evaluation and the past evaluation of the each unit interval on the map;
• and
• if a distance between the current position of the vehicle and a display position of at least one past evaluation on the map becomes equal to or smaller than a predetermined distance, erasing the at least one past evaluation from the map.

A non-transitory computer-readable storage medium that stores computer-executable instructions for performing an evaluation display function comprising:

• displaying a current position of a vehicle and a map around the current position on a display unit;
• acquiring a current evaluation indicating a fuel efficiency evaluation of each unit interval in a current travel of the vehicle;
• acquiring a past evaluation indicating a fuel efficiency evaluation of the each unit interval in a past travel that is earlier than the current travel;
• displaying the current evaluation and the past evaluation of the each unit interval on the map;
• and
• if a distance between the current position of the vehicle and a display position of at least one past evaluation on the map becomes equal to or smaller than a predetermined distance, erasing the at least one past evaluation from the map.
