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.
