Good night,
I've been studying a bit more about LaTeX, more specifically about TikZ and how to create images with it and I've come across this image on the manual:
The image above is on the 90th page of the manual (V 2.10).
The image above got my interest because I might teach statistics next semester and this could be a different way of showing data to my students but I didn't find it's code in the manual so I could study it (I'm afraid of having missed it though).
How can I draw something similar to that in TikZ? Thanks in advance.
