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)
