How can I let Matlab automatically insert line breaks in my legend when specifying a legend width?

Hi, I am creating a GUI in which a figure is created with a plot with multiple lines, of which each line represents a dataset with a name specified by the input of the GUI.

I want to add a legend at the right of my plot with the full name of every line. I then try to set the legend position so, that it just fits inside the figure window. handles.datanames is a cell containing 1 name of a dataset per element.

h_legend = legend(handles.axes, handles.datanames);
set(h_legend, 'Interpreter', 'none');
set(h_legend, 'units','normalized', 'position',[0.75 0.11 0.07 0.5]);

However, when one of the user specified names is longer than fits inside a legend line, the legend automatically stretches outside the figure window along with the name, instead of using a line break.

I know that I can manually insert a line break with /n, but how, if possible, can I let Matlab do this automatically at the end of the legend box?

Thanks,

Max
