A nice feature would be to display SOC on the chart with a logarithmic scale
Lou Little commented
Show not only the SOC value log rhythmically but also include the DC graphical values on the right because the values below half of the battery voltage is very seldom used. It would be nice to see the voltage swing more dramatic on the page. A logarithmic scale would probably be just the ticket! I am an off-grid user and battery voltage and SOC mean the most for me too watch.
