I'm using barChartPlotter to show power (kWh) values for each day and it works great.
Now I would like to put price (kWh value * 0.08) on y2 axis. So that on y axis I have kWh and on the right y2 axis price (but to have only 1 column). I tried adding extra y2 into axes option, but I cannot get it work without adding another series.
Is this possible?
It's not. You have to add another series.
