Legend is not working!

I think I have a simple problme. I have 4 plots in my code as you can see, however, it seems that Legend does not recognize my last plot.

show your legend and plot calls

Here is my code:

I = 0:0.001:0.1;

R1 = 95.7;
R2 = 198.33;

V1 = I * R1; 
V2 = I * R2;
V3 = 0:1:14;

plot(I,V1,'-k')

hold on

plot(I,V2,'-g')

plot(I,12,'-rx')

plot(0.1,V3,'-bo')
hold off


title('Voltage and Current')
legend('V(R1)','V(R2)','Voltage limit','current limit');
xlabel('Current DC (A)')
ylabel('Volatge DC (V)')

plot(I,repmat(12,1,numel(I)),'-rx')
plot(repmat(0.1,1,numel(V3)),V3,'-bo')
