Hi,
In previous versions of Matlab, I could append a legend if I wanted or not, using the following code. This was very handy in case I didn't have all handles of plots at the beginning and just wanted to append the list of new plots. Any idea how to do this in Matlab 2015?
Many thanks M
[LEGH,OBJH,OUTH,OUTM] = legend; % reading handles
LEGH = legend([OUTH;hnew],OUTM{:},'newPlotName'); % append new plot
where 'hnew' is the handle of the new plot and ''newPlotName' its name.

Here's an example of how to update the legend to include newly added plots.
% plot 3 lines and add a legend
p=plot(magic(3));
l=legend(p,'plot1','plot2','plot3');
% add a fourth line, specifying the DisplayName
hold on
plot([5 5 5],':','DisplayName','plot4')
% turn legend off and back on.
legend('off');
legend('on');

In my version(R2015b),
legend('on') did not work for me. It just created a legend named with 'on'. But 'show' just worked well.
legend('off')
legend('show')

%first get the legend handles
old_legend=findobj(gcf, 'Type', 'Legend');
%then append the legend with new entry
legend([old_legend.String,'new_entry'])
