WTH can't I specify the range of the graph on the energy dashboard

I would like to be able to select the axis range for the graphs in the energy dashboard. I think it is really confusing to see a big bar of my boiling water tap filling the whole screen in the section of individual devices when it only uses 0,5 kWh per day. When I run the wash machine that day the washer is the biggest bar with 1,0kWh. Please make is consistent and not dependent on the largest consumer of the selected time period.
