Hi Olga,

may be you can work around with the suggestions below, while other
provide the best solution for your:

barplot(c(1,2,3,5,2,3,1),names.arg=c("100","200","300","400","500","600","700"),
 xlab="diameter",ylab="flow",main="some title",space=0.1)
lines(lowess(c(1,2,3,5,2,3,1),f=1), type="b", lwd=2, lty=3, col="blue")
cheers
