Hi all,
I have the following arrays, I want to draw a horziontal line between each row. Could someone please teach me how to do that?
A = [5:1:45]
B = [10:1:50]
So what I want is a horzintal/flat line between each point of A and B. For instance a flat line for A(1)=5 at a Y of 1 extended to B(1)=10 at the same Y. Like the image below:

Not in time for me to see it and post an Answer.

Question is not clear. Quoting on a part of your question, " flat line for A(1)=5 at a Y of 1 extended to B(1)=10 at the same Y"
A and B should have the same dimension, and you must have a y values of corresponding A or B.
A=randi(10,1,6);
B=A+randi(5,1,6);
y=[1:6];
for ii=1:length(A)
plot([A(ii) B(ii)],ones(1,2)*y(ii),'k-o')
hold on
end
