Average line misaligned with Y axis

[Nikoleo]

Greetings everyone,

I'm having this grouped histogram showing measured values over a range of years, to which I added an simple average line using the analytic pane.

However, the data label of the line (which seems correct to me) is not matching the Y axis. Instead of being at 0.55, it shows closer to 0.51.

What am I missing?

Yes, you're totally right.

I looks like it is in the right place to me.  The mid point between 0.5 and 1.0 is 0.75, your line is at 0.55.
