Hi,

I have a problem.

I want to plot a figure in for-loop of unknown number of values.

*********************************

%%%%plot

    cc=hsv(nk12*nk21);
   jj=1;
   for kp=1:nk21
   for jp=1:nk12
   loglog(p,intensity1(:,jp,kp),p,intensity2(:,jp,kp),'color',cc(jj,:))
   ylabel('f^es');
   xlabel('t');
    title('Graph of intensity for  modes 1 and 2')
    set(gca, 'XScale', 'log', 'YScale', 'log')
    jj=jj+1;
    hold all
    [~,~,~,names] = legend;
    legend([names {sprintf('%s%g','k12,k21=',jp,',',kp)}]);
end
end

*******************************************

How can I arrange this so it plots a legend for each dataset?

First: your code is unreadable if you do not format it as code!

Second: As some variables are missing I cannot run the code, so I cannot guarantee that my answer really works. Try the following:

h = NaN(nk21*nk12,1);
hold on;
for kp=1:nk21
   for jp=1:nk12
      h(jj) = loglog(p,intensity1(:,jp,kp),p,intensity2(:,jp,kp),'color',cc(jj,:)) ;
      jj=jj+1; 
   end 
end
legend(h, s,u,'Location','southeast')
