Can somebody smarter than me tell me what this is trying to say? There’s a bar for surveillance year and birth year. But, for instance, 2012 is on the graph twice with different values. What does it mean?

Edit:

I think I got it. The graph is of “Autism rates in 8 year olds over time”. And the X axis should just be year (in 2 year increments).

    2012 appears once as a birth year and once as a surveillance year. The graph says that they only ever surveyed 8-year-olds, since the birth year is always 8 less than the surveillance year.

    But they have 12 bars and 6 labels... it makes no sense

    I see 6 labels. I guess that means 2 surveys per year. But I’m just guessing.

    It's probably a dataset that collected every 2 years, but only labeled every other bar to prevent the graph from being overcrowded.

    Not a great decision, but not terrible.

    Although, I'm a bit concerned for Lemmys graph comprehension skills.

    Bad graph, they couldn’t decide if the X axis was the birth year of the kids or the year of the test but they give the same information since it’s always 8-year-old kids being tested. Anyways, they wrote the year of the test first and second the year of birth.
