@shortstories I bookmarked this because it annoyed me and I wanted to fix it but forgot and spotted it again while going through my bookmarks for something else. Whoever plotted this data is capital R retarded so I fixed it by re-entering the data from the plotted bins in by hand and re plotted it in matplotlib (this only took like 5min probably in my defense otherwise I wouldn't have bothered). This is what it should have looked like if plotted in a more typical way.
The point was mainly that the original figure was kind of garbage because it doesn't intuitively show the data in a sane way since they showed the IQ value and population percentage as two different colored bar graphs in the same figure. Normally you want it to look like the figure I generated because then you can actually see the actual distribution (which shows the relationship between the random variable measured, here IQ, and the probability/percentage of different values).
