Legend in plot with a loop

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

Thank you for the answer.

It gives numbers as 1 to 48 as in the figure ans attached to this reply. But, I want to have these co-ordinates in figure coord attached.

Then just modify the above code as follows:

Instead of:

name = ['Flux densities at ', num2str(j)];

Use:

name = ['Flux densities at ', num2str(a(1,j),',', num2str(a(2,j)];

where a is your coordinate vector.

Answer 2

my matlab code and workspace is attached. It is still not working.

There's an error because one bracket is not closed.

name = ['Flux densities at ', num2str(a(1,j),',', num2str(a(2,j))];

It works fine for me now.

Thank you so much.
