mesh plot with lines only

Hi,

I'm trying to plot 2 lines using the mesh function,

This is what I hoping to achieve. This example graph has 45 lines.

I don't really know what to do, if I import the data as column vectors like this:

x = load('x.txt.');
y1 = load('y1.txt.');
y2 = load('y2.txt.');

Could somebody advise me what the command would be to plot them using the mesh function.

I've searched online but cannot find an example similar to this. I just need to be pointed in the right direction.

Thank you

In the simplest case you have some data

M = 2;
N = 10;
x = 1:N;
y = 1:M;
z = randn(M, N);

and you create a mesh

mesh(x, y, z);

For you, assuming the text files are the correct sizes ...

M = 2;
y = 1:M;

x = load('x.txt');
N = length(x);

z = zeros(M, N);
for ii = 1:M
  z(ii, :) = load(['y', num2str(ii), '.txt']);
end

Instead of mesh maybe you want

plot3(x, y'*ones(1, N), z)

Hi, thank you for the help,

Something is going wrong though, it might the format of my text files.

This is what I'm getting:

The text files have the following format: x is a column vector of time values, with values 0-23 (hrs) y1 is a column vector of velocity, with 24 different values y2 is a column vector of velocity, with 24 different values also

I am hoping to achieve something like this, excuse the artwork!

I edited my question to include a plot3 option. Is that more what you are looking for?

many thanks
