Dear All,
Thanks everyone for your kind responses.
Now I understand what is gong on! I guess that the question asked is
wrong in the first place.
As there is a categorical list of groups and their values (a range of
pipe diameters and a flow for each diameter), and a barplot would be a

Sounds like a fortune to me! :-)

You have three problems:
i) Barplot's plot locations are not at 100-700 in your picture.
ii) density applied to your bar hights will produce the density as if
those are x locations, not heights.
iii) density's height is scaled to unit area and not the height of your
bars.
And a statistical issue:
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"),
