How can I display the legend at my desired side outside the figure? I run the following code but it doesn't work:
clear all; close all; clc
one=rand(100,1);
fitness2sn0=one';
one=rand(100,1);
fitness2sn5=one';
one=rand(100,1);
fitness2sn10=one';
one=rand(100,1);
fitness2sn15=one';
fitness2sn0=sort(fitness2sn0,'descend');
fitness2sn5=sort(fitness2sn5,'descend');
fitness2sn10=sort(fitness2sn10,'descend');
fitness2sn15=sort(fitness2sn15,'descend');
h1=boxplot([fitness2sn0; fitness2sn5; fitness2sn10; fitness2sn15].');
set(h1,{'linew'},{2})
grid
Ax = gca;
Ax.YLabel.String = '\bf fitness';
Ax.YScale = 'log';
Ax.XTickLabel = compose('2sn%d',[35 45 55 65]);
Ax.YLim = [1E-3 1e0];
title('\bf Fitness')
set(gca,'linew',2)
lgd = legend('35dB', '45dB','55dB','65dB')
lgd.Location = 'southoutside';

and do the modification like the following:
one=rand(100,1);
fitness2sn0=one';
one=rand(100,1);
fitness2sn5=one';
one=rand(100,1);
fitness2sn10=one';
one=rand(100,1);
fitness2sn15=one';
fitness2sn0=sort(fitness2sn0,'descend');
fitness2sn5=sort(fitness2sn5,'descend');
fitness2sn10=sort(fitness2sn10,'descend');
fitness2sn15=sort(fitness2sn15,'descend');
colors = [1 0 0; 0 0.5 0; 0.5 0 0; 0 0 0.5]; % Add different color
h1=boxplot([fitness2sn0; fitness2sn5; fitness2sn10; fitness2sn15]','Colors',colors);
set(h1,{'linew'},{2})
grid
Ax = gca;
Ax.YLabel.String = '\bf fitness';
Ax.YScale = 'log';
Ax.XTickLabel = compose('2sn%d',[35 45 55 65]);
Ax.YLim = [1E-3 1e0];
title('\bf Fitness')
set(gca,'linew',2)
hChildren = findall(gca,'Tag','Box');
lgd = legend(hChildren([4 3 2 1]), {'35dB','45dB','55dB','65dB'});
lgd.Location = 'southoutside';

Simon's answer is the core of any solution to this problem, so it's appropriate that he gets credit. While it's sometimes unfortunate that comments can't be upvoted for emphasis, your comment is verification that it helped. That much is sufficient for my needs, and it should help any future readers with the same problem.
Thanks a lot for your kind words dear DGM. Well said.
