I might miss the point, but the height is dependent on both parents genetically, so just comparing mothers with daughters is a bit like the usual "correlation does not equal causation" thingie, or not?
That's exactly what this is showing. The x axis is the fathers height and the y-axis the mothers height so you see daughters change of being taller going up when their dads are bigger. For sons the chance of being bigger than their father goes up with tall mothers.

The X and Y are just labeled weird, both graphs reference father's height has the X and mother's height as the Y
Yeah, but there is no graph comparing son vs mother and daughter vs father.
And it seems like an odd thing to omit.
If I'm reading the referenced link right, the data is from 1886(?), so it's not terribly recent, either.
Wow, thanks for checking on that
yes, 928 children and 205 parents it seems.
wonder how the trend shown here has changed in almost 150 years...
Oh, completely missed that, thanks!
