Option to display fuel use chart by distance or time
Currently the chart shows fuel efficiency (vertical axis) compared to time (horizontal axis). It would be good if one could toggle this with distance. So distance between the dots and then an estimated or exact odometer (total distance) depending on how the user is inputting their distance. As engines get older or are run in or after a particular service / oil change, do they become moree or less efficient? If one thinks about it the state / age of the engine is probably a key determinant and something one should track, but it doesn't seem to be represented anywhere....??
