The graph only shows the relationship between the frequency of service and the number of passengers. It does not take into account other factors that could potentially affect passenger numbers, such as time of day, day of week, location, or fare prices. Therefore, it would not be accurate to conclude that no other factors besides frequency of service affect passenger numbers.
