Hi,
Keep your emails on the list, please.
here are some artificial data
dput(dat)
structure(list(x = c("a", "a", "a", "b",
"b", "b"), y = c(1,
1, 1, 3, 3, 3), cond = c("x1", "x2", "x3",
"y1", "y2", "y3")), row.names =
c(NA,
6L), class = "data.frame")
And possible result
hist <- ggplot(dat, aes(x=x, y=y, fill=cond, stat="identity"))
hist + geom_col(width=0.4, position = position_dodge(width=0.5))
You could change colour scheme
https://stackoverflow.com/questions/18229835/how-do-i-manually-set-geom-bar-fill-color-in-ggplot
hist + geom_col(width=0.4, position = position_dodge(width=0.5))+
scale_fill_manual(values=rep(c("red", "blue"), each=3))
Cheers

Hi Petr
Thank you for reply. I used this link
(https://stackoverflow.com/questions/6085238/adding-space-between-bars-in-ggplot2)
for separating bars, but it doesnt work for my purpose. since I have same
levels for one group, with this code, the bars are connected together: as a
bar for one group. While I want to add some space between three bars belong to
one group.
I really appreciate if you can help me
Sincerely
Azam

Adding space between bars in ggplot2
I'd like to add spaces between bars in ggplot2. This page offers one
