I have confirmed that the cset by Rik made figure size changeable for qt 
terminal.          

__gnuplot_drawnow__.m (line 226)


if (strcmp (term, "x11") || strcmpi (term, "windows"))

i
V

if (strcmp (term, "x11") || strcmpi (term, "windows") || strcmp (term, "qt"))



For the position option  implementation qt is simple but for wxt one should 
also check gnuplot version.
(require >= 4.6.4 ).
