Adding to a legend after each iteration

Question

I run

loglog(x,y);
legend(\'First script\');

from the first script. Then, hold on;. I run a similar second script. I see two g

Answer 1

Another possible way to do this and it is called 'DisplayName':

hold all
for ind=1:3
x=[0:0.1:10];
plot(x, sin(x)+ind, 'DisplayName',['sin + ' num2str(ind)]);
end
legend(gca,'show')

Just use this property when plotting from wherever to whatever axes :)

There are even more things possible, like dynamic legend!

For more information see this: dynamic legend from undocumented matlab

EDIT

you have to update the legend after every run of a script. you can do this with the dynamic legend or by just legend('off'); legend('show')
