The problem I see here is that you are trying to use functions at all. Take the years/GDP line. If your measure the GDP once a year, you should use a bloc graphic.
Else you have a lot of imaginary points per month, day and hour, that, in reality, are not there. Take black friday—lots of changing , take holidays, when the shops are closed—little changing.
Days—lots of changing, nights—little changing. And you can´t really know the GDP for the next year—there can always be a drastic change.
Take the cannabis/homeowner plot graph on the other hand. You have a lot of (x,y) pairs (homeowners, cannabis supporters)
Some of these points have the same place on the x—axis, but different places on the y—axis. That is the reason you can´t just draw a function through all this points.
Such a set of points is called a relation in mathematics. Just because you can draw a line through them does not mean you should.
And just because it is customary to draw orthogonal x- and y- axes in mathematics does not mean that is always the best way.
Especially If the points of a relation are not stochastically independent it might not be a good idea.
After all, you draw on a euclidean plane and your are free which axes to chose on a euclidean plane.
