Hi.
I want to remove the legends for my vertical dash plots (data1 to data5!) . Here is my code:
figure (11)
for i=1:n1
plot(f{n1-i+1},Sx_dB{n1-i+1},'DisplayName',['Node ',num2str(n1-i+1)])
xlabel('Frequency (Hz)');
ylabel('Acceleration PSD (dB)');
title('Auto PSD')
xlim([0 round(max(w_Hz))+1])
legend
hold on
grid on
end
for j=1:n1-1
xline(w_Hz(j),'r--')
hold on
end
I would appreciate it if someone could help me with this.
Thanks,
Amir

for i=1:n1
plot_lin(i)=plot(f{n1-i+1},Sx_dB{n1-i+1},'DisplayName',['Node ',num2str(n1-i+1)])
xlabel('Frequency (Hz)');
ylabel('Acceleration PSD (dB)');
title('Auto PSD')
xlim([0 round(max(w_Hz))+1])
hold on
grid on
end
for j=1:n1-1
xline(w_Hz(j),'r--')
hold on
end
legend(plot_lin,{'data1 ','data 2','data 3','data 4','data 5','data 6'})
Make sure to have sufficient legend titles in the last line of the code.

Since I do not have the data, I am generating plot for random data.
clc
clear
for i=1:4
plot_lin(i)=plot(linspace(0,2*pi,100),sin(i*linspace(0,2*pi,100)),'DisplayName',['Node ',num2str(4-i+1)])
xlabel('Frequency (Hz)');
ylabel('Acceleration PSD (dB)');
title('Auto PSD')
% xlim([0 round(max(w_Hz))+1])
hold on
grid on
end
for j=1:5
xline(j,'r--')
hold on
end
% legend(plot_lin,{'data1 ','data 2','data 3','data 4','data 5','data 6'})
legend(plot_lin)
Above code is working fine, and generating this below plot
