Hi Kristen,

Unfortunately, Octave's handle graphics are not yet fully compatible  
with Matlab. The figure position property is only partially  
compatible. To place the figure you need to be running gnuplot 4.2.5  
or later and octave 3.2.x.

 When creating a figure, you can set the figure's position by

        figure (h, "position", [xLL, yLL, width, height])

For example ...

        figure(1,"position",get(0,"screensize")([3,4,3,4]).*[0.1 0.2 0.8 0.7])

Once the plot stream to gnuplot is open, it is no longer possible to  
can the the figures position (unless someone wants to write the  
necessary code to communicate with x11).
