MATLAB: How to plot connected points

Question

How do i plot(x,y) such that the points are connected to each other instead of from the origin ?

Answer 1

I was able to reproduce your problem:

x = [zeros(1,10); 1:10];                            % Simulate Data



x = x(:);                                           % Simulate Data
y = [zeros(1, 10); rand(1, 10)];                    % Simulate Data
y = y(:);                                           % Simulate Data
figure(1)
plot(x, y)                                          % Reproduces Problem
figure(2)
plot(x(x ~= 0), y(y ~= 0))                          % Fixes Problem

The solution is to take the non-zero values in both the x and y vectors, as I do in figure(2). That should give you the plot you want.
