Suppose I have data such as the following

tmp1<- data.frame(vars = with(tmp, c(var1, var2, var3)), type = gl(3, 100))
var3 is on a different scale, but I create the following plot, which looks terrible as a result
bwplot(~ vars|type, tmp1,
layout = c(1,3),
)
Of course, I can use the scales = 'free' argument and this looks fine.
bwplot(~ vars|type, tmp1,
scales = 'free',
layout = c(1,3),
)

The scales = 'free' argument permits for each plot to have its

Does this help:
bwplot(~ vars|type, layout = c(1,3), data=tmp1
, scales = 'free'
, xlim=list(c(-3,3), c(-3,3), c(-60,90))
)
There's a comment on ?xyplot in the scales section:
"When relation is "free", xlim or ylim can be a list, ..."
