Round battery voltage to calm down graph #79

The voltage level toggels between some micro levels which makes the graph unreadable.

I would suggest to keep as much information as possible in the database for future debugging reasons. (Also a voltage step discretization of less than 0.1V is necessary to determine the battery level.)

One possible solution would be to adjust the graph scales to a fix range.

Bat. volt. 3V - 4.2V
Bat. level 0% - 100%)

I think this would tidy up the graph enough to make it better readable.

Scaltes to fixed range did the trick.
