Hello,
In base graphics function barplot has arguments angle and density, see
the help page ?barplot. As an example, with the same data (note that the
argument density is recycled, 2 values, one per stacked bar times the
number of unique X vakues):
barplot(Freq ~ Y + X, tbl, density = c(10, 0))
Hope this helps,
Rui Barradas

Thanks Rui. That's very close to what I am looking for. You use gray
scales for different categories. That would be a great idea. Could we
use pattern fill?

Hello,
Without sample data and the code you've tried it's difficult to say but
are you looking for something like this?
set.seed(2020)
df1 <- expand.grid(X = factor(1:5), Y = LETTERS[1:2])
df1 <- df1[sample(nrow(df1), 100, TRUE), ]
library(ggplot2)
tbl <- as.data.frame(table(df1))
ggplot(tbl, aes(X, Freq, color = Y, fill = Y)) +
geom_col() +
scale_color_manual(values = c("black", "black")) +
scale_fill_manual(values = c("white", "gray70")) +
theme_bw()
Hope this helps,
