I haven't used MATLAB in a while but last time I tried, I didn't have any issues with plotting function. Now when I am plotting and adding a title to the legend, apparently as shown below, It won't show up! Any suggestions toward fixing this issue would be greatly appreciated?!
clear, clc, clf, cla reset, format shortg,
g_compress = CompressExtract('CompressExtract.csv',2,1000);
g_table = g_compress(:,[1,12]);
g_Bins = g_table(:,1);
g_RSCP = g_table(:,2);
plot(g_Bins,g_RSCP,'-','Color',[0.5, 0, 0], ...
'LineWidth',1,'LineSmoothing','on')
lgd = legend('Example','Location','S');
title(lgd,'My Legend Title')
axis([0 1000 -100 -40]), grid on

Hi,
Normally for title
title(str)
title(str,Name,Value)
title(ax,___)
but the value of
lgd = legend('Example','Location','S');
is not a string or axis details.
I think you should just use 'legend(your specifications)' to locate the legend details on the graph and then add the title name.
Thanks.

In R2014a and before, legend() returned an axes handle, and you were able to title() against that handle.
In R2014b and newer, it turns out that you can set a Title property:
http://www.mathworks.com/matlabcentral/answers/304014-unable-to-add-title-to-legend#comment_393200
lgd.Title.String = 'My Legend Title';
In R2014a and before, there is the question of whether the default position is within the portion being displayed, and similar concerns. The way legends were constructed in R2014a and before was not expecting a title to be added.

Thanks to both of you for your explanation. Here is what I improved;
clear, clc, clf, cla reset, format shortg,
g_compress = CompressExtract('CompressExtract.csv',2,1000);
g_table = g_compress(:,[1,12]);
g_Bins = g_table(:,1);
g_RSCP = g_table(:,2);
plot(g_Bins,g_RSCP,'-','Color',[0.5, 0, 0], ...
'LineWidth',1,'LineSmoothing','on')
lgd = legend('Example','Location','S');
lgd_title = get(gca,'title');
set(lgd_title, 'string', 'LegendTitle','FontWeight', 'Bold')
title(lgd,'My Legend Title')
axis([0 1000 -100 -40])
Here is how it looks like, my question to you both, how do I turn the box on around the legend title?
