Reduce legend size
Daniel Wesemeier
I intend to produce Matlab figures which are about 8cm wide on a page generated with LaTeX. After resizing the figure the legend appears quite big and the legend covers a lot of my plot. The font size can easily be changed by the "FontSize" property. And I found a thread which shows how the sample lines can be reduced in length. (http://www.mathworks.com/matlabcentral/newsreader/view_thread/155063#389116)
Here is the Problem: After I have resized the legend sample line length I tried to reduce the size of the legend box via the legend's "Position" property. But the size can only be increased but not decreased.
Is there a way to decrease the size of the legend box?
Thanks!

take the black cursor from the toolbar.
left-click on the legend corner
right-click and select 'unlock axex position' or something like this ...

You'll have to post how exactly you used 'Position' to resize the
legend box. I do this all the time and have no problems, so in
principle what you are doing is correct, but the actual implementation
may be wrong.

Thank you for your answers. Somehow I missed the notification. And I found a work around. I resized the Matlab figure twice the size I required and scaled it by half via LaTeX. So I forgot to come back to this thread. But now it turns out this work around has a little troubles when the figure is resized in LaTeX again.

I change the Position via get(...,'Position') and set(...,'Position',...).
here is an example:
AllObjects = findobj(gcf);
% Find the legend objects
alllegends = findall(AllObjects,'Tag','legend')
% Identify the legend content
childs = get(alllegends(1),'Children')
n_legent = length(childs);
allmarkers = childs(1:3:n_legent)
alllines = childs(2:3:n_legent)
alltext = childs(3:3:n_legent)
% Readjusting the linest
for it = 1:length(alllines)
xcor = get(alllines(it),'xdata')
leftshift = (xcor(2)-xcor(1))/2;
set(alllines(it),'xdata',[xcor(1) xcor(1)+(xcor(2)-xcor(1))/2]);
end
% Readjusting the text
for it = 1:length(alltext)
pos = get(alltext(it),'Position');
set(alltext(it),'Position',[pos(1)-leftshift pos(2)]);
end
% Change the Position Property
posleg = get(alllegends(1),'Position')
set(alllegends(1),'Position',[posleg(1) posleg(2) posleg(3)-leftshift posleg(4)]);
@Nicolaie Popescu-Bodorin
There is an "Edit Plot" tool and a "Data Cursor" tool. But neither has an "unlock axes option" in its content menu.
Has anyone another hint? Is the a hidden property somewhere that prevent the legend from be resized to small?
(By the way: I am still using Matlab 2007b. Maybe that is the problem.)

one of the (tedious) solutions
x=0:360;
y=sort(rand(size(x)));
line(x,y);
lh=legend('a');
disp('press any key to make legend smaller...');
pause;
set(lh,'units','pixels');
lp=get(lh,'outerposition');
set(lh,'outerposition',[lp(1:2),50,15]);

work's! Very nice. So the trick is to change the 'units'. Thanks
Jan.

Another trick is to change the plot to box aspect ratio.
legend('string','Plotboxaspectratio',[0.8 0.8 0.8])
The numbers in the brackets are x y and z aspect ratio between the plot and the legend box
This way you will decrease to 80% the size of the legend box.
The thing is that you might need to change the font size as well to make it fit within the box. To do so, you can just add 'Fontsize',size_number within the legend command.
Hope this helps,
Anthony
