More readable electricity history graph

[SqFKYo]

TL;DR

Having a sum energy usage and ticks on energy consumption would make it much clearer.

What ?

The electricity graph (when clicking power pole) should have sum graph as well as clearly labeled y axis, so it's easier to see the scale of things.

After with sum (white line) added:

Why ?

The history is currently fairly hard to read and plan with. These changes would make engineers happy and planning easier.

A few grid lines coming from the Y-axis to help you line up numbers would be nice too.
