That's because you misunderstood the relation between 'set yrange' and 
'set autoscale'.  In particular, 'set autoscale ymax' will not make any 
difference at all if you never 'set yrange' to some particular value 
before.  The effect you want is most directly obtained by

	set yrange [0:*]

The start-up default for both axes in gnuplot is 'autoscale' with a 
fall-back of [-10:10] for the x range in case you plot only an explicit 
function, without giving any x range.  'set autoscale ymax' in that 
situation has no effect, because the upper end of the yrange is already 
set to be autoscaled.

The problem with your script is that you never mentioned, anywhere, that 
the y axis was supposed to start at 0.
