how to do superimposing?

for m=1:5
    figure(2); subplot(3,3,m); 
    plot(Jan_global(:,n));ylim([0 400]);xlim([0 120]);title(B(1,x));ylabel('Irradiance');xlabel('Time');
    set(gca,'XTickLabel',{'7.45';'13.00';'17.00';});
    set(groot,'defaultLineLineWidth',1.5)
    m=m+1;
    n=n+1;
    x=x+1;
end

I'm having code to create a multiple graphs using the loop.

How do I superimpose the mean value graph in that same graph?

What change do I need to make in that code.
