Try this:
plot(Y2(1:21,13), Z2plot(1:21,13), 'r-', 'LineWidth', 2);
hold on;
plot(Y1(1:21,13), Z1plot(1:21,13), 'g-', 'LineWidth', 2);
plot(Y(1:21,13), Zplot(1:21,13), 'b-', 'LineWidth', 2););
grid on;
xlabel('\fontsize{20}X - Pixels');
ylabel('\fontsize{20}Z plot');
title('\fontsize{22}integration 64*32');
legend('Z2plot', 'Z1plot', 'Zplot');
