I did how to draw a line along the coordinates, but I don’t know how to color it.
a=[110 120 70 140 150]
b=[20 30 40 50 80]
red=[3 2 1 2 3]
plot(a,b)

it shows how this can be done in another program. I have such a question, is it possible to do this in Matlab ???
p.s. the main thing is that on the line it would be possible to distinguish between changes

How does the red array correspond to changes in the color of the line? You change color at about 83 or so, but none of your variables have value that is about 83, and you change back around 108 or so; that could plausibly be at the same 110 as your first a value, but you do not have any 110 coded in the middle of an array that might signal a change at that location.

a=[110 120 70 140 150]
b=[20 30 40 50 80]
red=[3 2 1 2 3]
plot(a,b,'r','linewidth',10)
%........^ color..........^ width of the line
