[Feature Request] Improve Battery Graph

[aheider]

The Battery Graph ist great, for one!
However, IT could BE greately improved, If IT head a grid which clearly indicated either different days or hours of the day. Also a linear Regression pointing Out how Long the Ring would Last, also giving this AS an estimate in hours.

Thanks.
