The width of the bars is computed from the minimum distance between any two
adjacent bars, so I would expect that somewhere in your data you have two
domain values that are closer than you expected. This is true even before
the viewWindow constraints are applied, I believe.

I have a stacked column chart. The bars are set at 75%.
var defaultGraphOptions = {
legend: { position: 'top', maxLines: 2 },
title: '',
height:400,
width:800,
chartArea: {left:"15%",top:40,width:"90%",height:"80%"},
isStacked: true,
bar: { groupWidth: '75%' },
