Hi Jerry,
I'm afraid there's no way to currently get the value of that resource.
The documentation of this resource is wrong, because it states that it
should be a value between 0 and 1, but really, it should be a value
relative the spacing of your X values.
For example, if your X values are 0, 5, 10, 15, ..., then
by default gsnXYBarChartWidth will be equal to 5, because the
spacing of your X values is 5.
So, to get a bar width that is half the default width, use a value
that is half the spacing of your X values: in this case, 2.5.
I'll go fix the documentation for this resource.
