I suppose some would say you deserve what you get and that it doesn't
really make sense to describe such data with barplots...
However, if you insist, try something like:
x<-c(-20,-22,-21,-28)
names(x)<-c("eenie","meenie","miney","moe")
barplot(-x-18,beside=T,ylim=c(0,12),axes=F)
axis(2,at=seq(0,12,2),labels=seq(-18,-30,-2))
