Smart Shunt Trends Graph Pinkish Line

Hi all I have a question about my smart shunt readout in the app, in the trends graph I have ah and state of charge % but also a pinkish line appears kind of randomly that I cant figure out what it represents.

The system is in my vehicle been sitting idle for 5 days inside a dark shed, as shown there was no energy / amps going in or out on this day and state of charge constant at 100%

Any tips would be appreciated, cheers.

Not to worry about that line, seems like a small bug in the software. That line represents the energy out, but the quantity is less than the scale graduations can express. Hence the left scale going from 0.0 to 0.0 .
