Show zero on economy graph
Posted: Tue Jul 07, 2015 4:34 amI noticed this recently and thought I should speak up: the current economy graph is truncated at an arbitrary number. Truncating the graph like this makes it difficult to judge the economy curve by eye. Even if the result is less detailed, I think a better visual representation of the proportional changes of economy over the engine RPM range would make for a more informative display.
Take, for example, the following two charts:
In the first chart, fuel consumption at 500 RPM is about a third more than at max efficiency RPMs. In the second chart, it is almost double. But you can't tell that by eyeballing, because the first chart is truncated at 300 g/kWh and the second at 250 g/kWh - in both charts, all you can see is that it is more than fuel consumption at redline.
