Pick one of the four signals, say vt1, and assume you have the time values in an array called t. Then plot it:

plot(t, Vt1, 'y-', 'LineWidth', 2);
ylabel('Vt1 (m/sec)', 'FontSize', 16);
xlabel('Time (s)', 'FontSize', 16);

If you want the others, do

hold on;
plot(t, Vt2, 'r-', 'LineWidth', 2);
plot(t, Vt3, 'k-', 'LineWidth', 2);
plot(t, Vt4, 'b-', 'LineWidth', 2);
ylabel('Vt1, Vt2, Vt3 and Vt4 (m/sec)', 'FontSize', 16);
xlabel('Time (s)', 'FontSize', 16);
legend('Vt1', Vt2', 'Vt3', 'Vt4');

This is a random signal

y=rand(1,10)
plot(y)
