Break long text in Matlab legend using plotyy

The legend in my plot is too long, how can I break it into two lines? I'm plotting using plotyy and used this code: 

leg = sprintf('I_{fitting}=I_0/(\surd{2\pi}\sigma)e^{-[t-t_0]^2/(2.\sigma^2)};\nso t_0=0.2\mus;\sigma=0.09\mus;I_0=4.8\cdot10^{10}W/cm^2') 
legend([h1 h2], 'I=10^{14}[T_e/(3680(1.054)^{1/3})]^{1.5}',leg);

Can you tell me what the problem is?

Do you get any warnings when you plot? Are you changing the Interpreter? Please provide an example where you actually call plotyy and determine h1 and h2. - horchler
please look at on my previous question, I am trying to make this kind of broken legend there [link]{stackoverflow.com/questions/21862835/…} - user3271929
Please edit this question to be clear about the exact nature of the problem and provide a simple runnable example that demonstrates it. StackOverflow works best when you do a bit of work to help us help you. - horchler

Try this

>> leg = sprintf('This is a really long line\nso I broke it in two')
>> plot(1:10, 1:10)
>> legend(leg)

Which results in

This won't work if there are other characters in your legend that need to be escaped (e.g. if there is a lot of LaTeX). In that case you can insert a newline character manually -

>> newline = char(10);
>> leg = ['This is the first line', newline, 'and the second: A = 2\pi r^2'];
>> plot(1:10, 1:10);
>> legend(leg)

which results in
