Logarithmic axis for Energy Dashboard (and other views)

If you charge an Electric Car, it will make the Energy Dashboard basically useless, since the addded Energy is so big that all other bars of sensors get tiny compared to the bar of the car. See attached images:
The green bar represents 7 kWh what is not a lot of energy. I.e. the bar could be easily 7 times the size (at least for the horizontal bar chart) what would render the chart completely useless.

A great help would be, if one could configure a logarithmic x- and/or y-axis (maybe log2, log10) for these views. Actually whenever displaying graphs, a logarithmic option would be great. You never know when it is useful.
