Error in legends of subplots using a for loop

I want legends g_1=fr(1), g_1=fr(2), g_1=fr(3) for each plots in each window ha(kk). I am doing some mistake in legends, but couldn't figured it out. Any suggestions please. Thanks.

[ha, pos]= tight_subplot(4,3,[.1 .15],[.13 .01],[.13 .1]);
fr=([0.1, 0.5, 1]);
[h0, h1]=size(fr);
% for jj=1:h1
    for jj=1:3
    for kk=1:12
        lin={'--','-.',':'};
        axes(ha(kk));
        x=load(sprintf('frq_%d%d.dat',jj,kk));
        x1(jj)=loglog(x(:,33),x(:,kk+5),'linestyle',lin{jj},'LineWidth', 2.5);
        hold on
        ylabel([ha(1),ha(4), ha(7),ha(10)],'\Delta\omega_{}')
        xlabel([ha(10), ha(11),ha(12)],'\Delta\omega_{o}')
        % legend([x1([1 2 3])],{'$g_1=fr(%d)$',jj},'Fontsize',34,'Location','northwest','Interpreter', 'latex');
        legend([x1([jj])],{'\rm{"$g_1{'+fr{jj}+'}$"}'},'Fontsize',34,'Location','northwest','Interpreter', 'latex');
        legend('boxoff')    
    end
end

Hello @Anil,

Without the 'frq_%d%d.dat' files, I will not be able to recreate the plots at my end to provide an accurate solution. However, I have provided one approach to format the legend as per my understanding in the code snippet below.

legendString = sprintf('\\it{g_{1}=fr(%1.1f)}', fr(jj));
legend(x1(jj), legendString, 'FontSize', 34, 'Location', 'northwest', 'Interpreter', 'latex');
legend('boxoff')

Hi Shivani,

Thanks for that.

I used

legendString =sprintf('$g_1=%f $',fr(jj));

to get g_1=0.1 , g_1=0.5 and so on, which wokrs for me. But it gets overwritten for next value of jj and doesn't show a separate legend for that. Any suggestions, please. Thanks.
