Can't plot certain measurements with statistics enabled

[andrzej-r]

I was happily using the plotly card for plotting power entities with statistics enabled. Then, I tried doing the same with other measurements (kWh, %, temperature etc) and I found they were not plotted at all. When I disabled statistics for that waveform it got plotted just fine. Any ideas what may be getting wrong or how to debug it? I do not see any error messages.

The code is a bit complicated but for the sake of completeness. The entity that is not plotted (unless I comment out statistic: section) is "SoC" - state of charge of battery in percents. I can see "SoC" showing up in the legend and the unit of axis y2 is changed to "%".
