While using xyplot or barchart, how does on move the x or y axis?  I am
trying to plot ratios ranging from 0.77 to 1.3 in a bargraph, with the y
axis at x = 1.  I want ratios greater than 1 to appear as on the right side of the y-axis
and the ratios less than 1 to appear on the left.


My dataframe US looks like this

State  Ratio

MA     1.3
CT     1.02
TX     0.9
AK     0.77

When I do barchart(formula = State ~ Ratio, data = US), the y axis is
positioned at x = 0.7.  How do I move it to x = 1?

Thanks,
Nirmala
