Hi, I am having a small probllem in adding a legend, I just can't get all the names for different frequencies:
clear all;
close all;
load psi_20.mat
load time_20.mat
psi_20 = psi;
time_20 = time;
plot(time_20,psi_20)
legend('20Hz')
hold on
load psi_40.mat
load time_40.mat
psi_40 = psi;
time_40 = time;
plot(time_40,psi_40)
legend('40Hz')
hold on
load psi_60.mat
load time_60.mat
psi_60 = psi;
time_60 = time;
plot(time_60,psi_60)
legend('60Hz')
hold on
load psi_80.mat
load time_80.mat
psi_80 = psi;
time_80 = time;
plot(time_80,psi_80)
legend('80Hz')
hold on
load psi_100.mat
load time_100.mat
psi_100 = psi;
time_100 = time;
plot(time_100,psi_100)
legend('100Hz')
hold on
I have matlab 2014b

hi
simplest code below - more sophisticated is always possible...
% simple code
load psi_20.mat
load time_20.mat
psi_20 = psi;
time_20 = time;
load psi_40.mat
load time_40.mat
psi_40 = psi;
time_40 = time;
load psi_60.mat
load time_60.mat
psi_60 = psi;
time_60 = time;
load psi_80.mat
load time_80.mat
psi_80 = psi;
time_80 = time;
load psi_100.mat
load time_100.mat
psi_100 = psi;
time_100 = time;
plot(time_20,psi_20,time_40,psi_40,time_60,psi_60,time_80,psi_80,time_100,psi_100);
legend('20Hz','40Hz','60Hz','80Hz','100Hz')

Don't use legend multiple times.
You can use this command after plotting all the plots.
legend('20Hz', '40Hz', '60Hz', '80Hz', '100Hz')
Hope this helps!
