I would like to display the odometer of my car as a curve. Now, of course, it is extremely boring to see a value that increases from 10,000 to 10,050 when I have driven 50 km. What makes more sense is a curve that shows how far or fast I drove and when. So if I drive for an hour on the highway at 130 km/h, the line must be at 130 km/h, when I then drive through the city at 50 km/h and when I park at 0. Not at one-hour intervals, of course, but at finer intervals, e.g. 5 minutes.

This is of course interesting for all incremental sensors, such as received internet data, natural gas or water consumption.

I canâ€™t imagine that nobody has thought of this yet, but I havenâ€™t found any good information on it.

With utility meters I always had the phenomenon that the curves fall to 0 at regular intervals and then rise again, forming a kind of sawtooth.

Has anyone ever managed to get this right?
