For ex.:

plot(x,sin(x));

[r, hobj1]=legend('sin(x)');

textobj = findobj(hobj1, 'type', 'line');

set(textobj,'???????????', 8); %Is there any lineProperty like 'lineLength'?

Thanks in advance!

When I try this in R2014a, two objects are returned into textobj, and the first seems to correspond to the line that is drawn in the legend. I can then access and change the length of the line with the following commands:

>> lineXData = get(textobj(1), 'XData');
>> lineXData(2) = 0.6;  % Change this line to give you the x coordinates you want
>> set(textobj(1), 'XData', lineXData);

The units for the legend are normalized, so you may have to figure out the unit conversion, but this should do the trick.
