Hi,

I have some data which plots 48 different figures for 48 different points. I want to have some kind of loop which can be used in the Legend command for the plotting so that I don't have to write the Legend for the figures. I have the 48 points in a variable =a in the workspace.

for j=1:48

figure;

normB48points=(normB(:,j));

plot(t',normB48points);

xlabel('time in seconds (t)');

ylabel('flux densities in Tesla (T)');

legend('flux densities at point');

end

Try this:

for j=1:48
        figure;    
        normB48points=(normB(:,j));    
        plot(t',normB48points);
        xlabel('time in seconds (t)');
        ylabel('flux densities in Tesla (T)');
        name = ['Flux densities at ', num2str(j)];
        legend(name);
end
