I have a graph with 18 horizontal lines, I need to first 6 lines to be colored magenta, the following 6 to be cyan and the last 6 to be red. Then I want to add a small label to that graph saying something like [0-6 = A], [6-12 = B] and [12-18 = C].
Is this possible?
Thank you.

Yes. Use the 'Color' option in line()
x1 = 0;
x2 = 20;
for y = 1 : 6
line([x1 x2], [y y], 'Color', 'm');
hold on;
end
for y = 7 : 12
line([x1 x2], [y y], 'Color', 'c');
end
for y = 13 : 18
line([x1 x2], [y y], 'Color', 'r');
end

Can you please elaborate? More especifically, what should I be doing? What is x1 and x2?

The above is fairly specific. line() is a MATLAB plotting call. Calling it with the parameter/value pairs shown will give you magenta or cyan or read lines.
