Confirmed.  I've re-titled to more specifically highlight what I believe the issue is.  plotyy() is a difficult function and is made more complicated by the addition of a legend object.  During the print routine Octave seems to be calculating the size of the figure incorrectly.

I'm attaching a copy of the script from comment #2 so testers can just download and run.  I'm all CC'ing the developer Pantxo who understands quite a bit about legend objects and printing.

Here is an script example which does not work on windows 10 with octave 6.1 release.
A generated svg file is attached
Quite interestingly, it works without "legend" command

function  test_saveas()
   close all
   f = figure;
   x1 = (0:0.1:12)';
   x2 = (0:0.01:10)';
   ysin = 100*sin(x1);
   ycos = 10*cos(x2);  
   [p1,h1,h2] = plotyy(x1,ysin ,x2,ycos);
   set(h2,'color','red') 
   set(h1,'color','black')
   set(p1(1),'fontsize', 18);
   set(p1(2),'fontsize', 18);
   xlabel('x')
   ylabel(p1(1),'100sin(x)')
   ylabel(p1(2),'10cos(x)')
   legend('100sin(x)','10cos(x)','Location','southeast')
   title('Test saveas function')

   saveas(f,'a.jpg')
   saveas(f,'a.svg')

end

Could you be more specific about the sequence of commands you use and the graphics toolkit you are using?  This works fine for me, albeit on Linux.

close all
graphics_toolkit qt
sombrero
# Use mouse to execute File Menu->Save As
# type in name "tst.ofig"
# type <RETURN>

The file is saved and there is are no changes to the displayed figure for me.

saveas function destroys current figure as saves it incorrectly
