Here are the screenshots with and without the option set size 1.3, 1.3.I remember that I spent some time with variable size in order to know if
it would be necessary to define an specific draw option for it. After
some empirical work, I decided it was completely useless due to the
behavior you are describing.
But what's wrong with Screenshot centerd.png? I suppose this picture has
been generated with the default values of size.
When the plot is generated, it may not fill the entire window until you
start to drag the mouse. If this is your problem, push on key "e" to
readjust the size of the plot.
