I'd be inclined to do a few more drives in it to see if the data starts recording as expected. No idea why it's only recording part of the journey and also if you look at your map, I would have expected that to have shown the route you had driven.Have I done something wrong, or is there simply not enough data there yet to compose the graphs accurately?
There could be a data connection issue between the car and your server, if you check the Teslamate is the car still showing as connected? Is your Tesla just called 'Car', if not that may indicate a problem (top left of your screenshot).
