Well the third time I was lucky?
I have the ecoRoute dongle that makes it possible to have the extra meters on the display of the Garmin.
I am using the fuel economy funktion (I am not sure it has enything to do with the dongle) and I want to use the live diagram with 10 minutes but it seems only the 5 hour diagram is live, the others are just showing the values of the moment when I choose it.
