I have an issue with switching the graph to dispaly in full or partial screen mode. The problem is that when sliding the graph left & right it will sometimes switch between these modes (full / partial) all by itself. And every time it switches modes I have to scroll from the beginning to find the interesting spot. So this is 2 problems: 1) accidental switching. 2) after switching - graph is reset to begining.
One tiny request: Could you *not* draw the Charger status on the graph? It appears to be a binary value anyway, so it is sufficient to show it by marking time axis in green.
