How to customize Legends?

figure
plot(1 , theta_tip_analytical_c1 , 'ro')
hold on
plot(2 , theta_tip_analytical_c2 , 'ro')
plot(3 , theta20g , 'ro')
plot(4 , theta_tip_analytical_c4 , 'ro')
xlabel('case no')
ylabel('theta tip')
title('Theta Tip Comparison')
%legend('analytical theta tip')
plot(1 , theta_tip_numerical_c1 , 'bx')
plot(2 , theta_tip_numerical_c2 , 'bx')
plot(3 , theta20n_c3 , 'bx')
plot(4 , theta_tip_numerical_c4 , 'bx')
legend('analytical theta tip' , 'numerical theta tip')
hold off

I want to name all those points plotted in 'ro' format as legend1 and all those points plotted in 'bx' format as legend2. How to do it?

Try this.. use handle structure as below

figure
p1 = plot(datax1,datay1 , 'ro')
hold on
plot(datax2,datay2, 'ro')
plot(datax3,datay3 , 'ro')
plot(datax4,datay4 , 'ro')
xlabel('case no')
ylabel('theta tip')
title('Theta Tip Comparison')
%legend('analytical theta tip')
p2 = plot(datax5,datay5, 'bx')
plot(datax6,datay6, 'bx')
plot(datax7,datay7, 'bx')
plot(datax8,datay8, 'bx')
legend([p1 p2],{'analytical theta tip' , 'numerical theta tip'})
hold off
