Below you show a function that creates a scatterplot
but it does not return anything. Sorry to nitpick but correct
terminology is quite important in understanding what you
are trying to achieve.

Do you mean displayed? Nothing is returned (or to be
pedantic, None is returned)

Again nothing is printed. Are you talking about the
displayed scatterplot?

Sadly neither do I, you need a mmatplotlib user
to answer that bit. The only reference to
colors I can see is the line
use_colors - 'rybg'
Which I assume stands for red, yellow, blue,green?
I further assume that the order is significant?
But I'm only guessing...
