I'm trying to plot data with the headers 1-8 as my y-axis and the day of year with time in the x-axis, to show something similar as the "Example.png".

As it turns out, stackedplot wants a timetable so I created ‘TT2’ for it.
Another option is tiledlayout and it came though successfully as well. I used a (4,2) layout here becaause otherwise they’re too small to see.
EDIT — Aesthetic fixes. Code unchanged.
EDIT — (1-Dec-2022 at 2:52).
Minor correction in ‘DOY’ calculation.
EDIT — (1 Dec 2022 at 12:54)
Created ‘VNT2’, updated ‘T2’.
