help multiple legends?

[sol]=aaa(@ptch);
    [x1,x2]=ptch(sol)
             plot(x1,x2,'r.-');hold on;
            xlabel('x1');ylabel('x2')
            legend('Modified');
    pause('on')
    fprintf('Press any key to continue to other algorithm')
    pause
    [Sol]=bbb(@ptch);
    [x1 x2]=ptch(Sol)
             plot(x1,x2,'k.-'); hold on;
            xlabel('x1');ylabel('x2')
            legend('pre modified');
    toc

how to display the legend in such a case?

[Azzi Abdelmalek]

What case?

That coding i posted...because only one legend comes and not 2

[Walter Roberson]

You legend once for every iteration of your for loops. You need 42 legend entries.

[JL555]

My bad let me edit the code

[Walter Roberson]

Are your x2 vectors or 2 dimensional arrays?

[JL555]

both x1 and x2 is 1x50 double

Answer 1

[Walter Roberson]

Do not call legend() twice. Call it once and pass in both entries.

yes walter i figured it out...by the way thanks anyway do you have any idea on pareto frontier for 2 objective functions?
