Seems to be a very recent issue. Likely related to a recent commit.

This seems to only work with the bar size between 3 or 6 months as well, smaller or larger don’t seem to break. Perhaps on smaller scales the points are too far apart to trigger the error, and on larger scales they’re too close together so some other function prevents them overlapping too much?

I tested it on Safari, iOS Version 16.6.1 on mobile rn, but it seems to work for me, whether 3, 6 months or any other period selected or not, I only get one set of rating points.

Here is what I see when I go to your profile and select the exact same day with the exact same graphs:

Similar result as @visualdenniss, tested on Safari iOS 16.7.12 but couldn't reproduce. Maybe it only affects new iOS?
