Rex,
I think this problem can be solved using xlim()/ylim() argument. Look at the
follwing code:
require(lattice)
da <- expand.grid(A=c("a","b"), x=1:4)
da$y <- c(1,5,6,3,2,0,6,0)
barchart(y~x|A, data=da, horizontal=FALSE)
barchart(y~x|A, data=da, horizontal=FALSE,
ylim=c(0, 1.05*max(da$y)))
At your disposal.
Walmes.
