plotting the trajectories of three particles in same graph

I have three particles with x and y values of each particle, I neet to plot all three trajectories in same graph. How can I do it?

Try this:

plot(x1, y1, 'r-', 'LineWidth', 3);
hold on;
plot(x2, y2, 'g-', 'LineWidth', 3);
plot(x3, y3, 'b-', 'LineWidth', 3);
grid on;
xlabel('x', 'FontSize', fontSize);
ylabel('y', 'FontSize', fontSize);
title('Demo by Image Analyst', 'FontSize', fontSize);
legend('y1', 'y2', 'y3');

I have time column as well but if it says to plot the trajectories of these particles. so do I have to include time as well.

[Image Analyst]

If all the x are the same time variable t, you can simply do

plot(t, y1, 'r-', 'LineWidth', 3);
hold on;
plot(t, y2, 'g-', 'LineWidth', 3);
plot(t, y3, 'b-', 'LineWidth', 3);
grid on;
xlabel('Time', 'FontSize', fontSize);
ylabel('y', 'FontSize', fontSize);
title('Demo by Image Analyst', 'FontSize', fontSize);
legend('y1', 'y2', 'y3');

Its variable t and with respect to t there is variable x and y for each three particle.

If x and y are parameterized variables depending on t, then the first code snippet I sent you will work.
