I'm assuming by this you mean barchart in the lattice package.

Some information on the form of your data would have helped.

This is not the standard form of a barchart, so you need to fudge some things. 
First of all, make the values in one of the groups (the ones you want on the 
left) negative. Then barchart with groups (or use + in the formula, depending 
on the form of your data), stack=TRUE should give you what you want. Of 
course, the axis labels will be negative, you need to control those using 
scales.
