Dear Cheikh Tidiane Wade

I would suggest using the ""ggpattern" package and his function geom_bar_pattern().

There are plenty of tutorials online, such as:

• https://statisticsglobe.com/ggpattern-r-package
• https://coolbutuseless.github.io/2020/04/01/introducing-ggpattern-pattern-fills-for-ggplot/
• https://stackoverflow.com/questions/62393159/how-can-i-add-hatches-stripes-or-another-pattern-or-texture-to-a-barplot-in-ggp

Here is an example of the finished product (credits to the stackoverflow user).

Don't use barplots. Better use interaction plots.

Thank you so much for replying. I got the ideas behind it. However, I wanted to use alone texture instead of colour for differenciating. Please check the picture in attached Ebrahim Ghaderpour Francesco Sanmarchi Jochen Wilhelm

Dear Cheikh Tidiane Wade

You can use the following code to set up a pattern for each group. You will need both the ggplot2 and ggpattern packages.

ggplot(data, aes(group, x)) + geom_bar_pattern(stat = "identity", pattern_color = "white", pattern_fill = "black", aes(pattern = group))

This should give you the desired result.

Best wishes,

Francesco

Dear @Francesco Sanmarchi, thank you for sharing the rcode. I was interested to know the code too.
