I have a matrix in which the values are mainly in the main diagonal. What i want to do is create a bigger matrix in which each row of the matrix is a line so it would show the values of each row across several lines. So for example if i have an identity 3x3 matrix, it would be three lines with spikes on the main diagonal.

The plot doesn't quite fit. But here take a look

Here's a custom plot type I made. It may look upside down, but the value on the y-axis denotes the row number. The "peak value" of the lines are scaled and only show relative height.
A = eye(5);
scale = 2;
figure;hold on
for j = 1:size(A,1);
y = A(j,:)./scale+j;
fill([1 1:size(A,1) size(A,1)],[min(y) y min(y)],'r');
end
If you prefer the reverse order, as they appear in the matrix, then just change the 5th line to
y = A(j,:)./scale+(size(A,1)-j);

I believe I adressed this in the original answer?
y = A(j,:)./scale+(size(A,1)-j);
