I want to add a legend in my plotting, in the explanation I want to add some kind of text 500 years, 1000 years, 2500 years and 5000 years.
My code is:
for i=1:length(Tm2)
plot(Tm1(:,1),(SA10(:,1)),'r');
hold on
plot(Tm1(:,1),(SA5(:,1)),'b');
hold on
plot(Tm1(:,1),(SA2(:,1)),'g');
hold on
plot(Tm1(:,1),(SA1(:,1)),'m');
hold on
title UniformHazardSpectra50Year
xlabel('time');
ylabel('Acceleration');
legend(500,1000,2500,5000);
end
Is there anybody can help me, why it doesn't works. The result is weird.
