Apexcharts card - Y annotation off

Configuration Frontend
1

I have configured a y-axis annotation for a card displaying weight but the line is a few pixels off. Does anybody have any idea, why?

It’s exactly where it should be. The issue is that your grid lines are spaced every 0.25 kg, but the labels are rounded to the nearest 0.1 kg.

Therefore the grid line labeled 105.0 is actually 104.95 but since only 1 decimal place is being shown it is rounded to 105.0.

I see, thanks.
