Too much information in one diagram. Only present the relevant information in your chart. in this case, it's the price difference, which is somewhat subjective because german gas stations change their price several times a day.

While I agree with your first part, the price difference is not subjective since every single gas station has to report their prices every time they change it and that information is publicly available. So the difference between average price at any given time and the individual prices is relevant information.
