How to move a lengend to the front with subplots

Hi have a figure with two subplots. The data for the legend comes from the top subplot. There is some empty space on the bottom subplot. When I drag the legend to the bottom subplot is disappears behind the plot.

I tried

I=legend({'$100 \hspace mm^{2}$'},'Location','southwest')
set(I, 'Interpreter', 'latex','Visible', 'on')
uistack(I,'up',200)

no joy

Are you using R2014b or later, or R2014a or earlier? legend() is implemented differently as of R2014b .

Did you try

uistack(I,'top')

Thanks. I tried

uistack(I,'top')

however the legend is still behind the lower sub plot. I am using 2015a.

Hi, I have the same problem and I use the following method to solve it:

figure()
subplot(2,2,2)...
subplot(2,2,3)...
subplot(2,2,4)...
subplot(2,1,1)...
legend('Put what you want here')
