Hi, I don't know the axis mecanism well enough in ggplot but using the original barplot function you can add an axis on the right using the axis function.
Here is an example: test <- as.table(matrix(c(2,10,3,11), 2,2)) barplot(test, beside = TRUE, col = scales::brewer_pal(palette = 1)(2)) axis(4, at = c(0, 5, 10), labels = c(0,50,100)) -----Message d'origine----- De : [email protected] <[email protected]> Envoyé : 24 novembre 2023 09:27 À : 'Charles-Édouard Giguère' <[email protected]>; [email protected] Objet : RE: [R] ggplot adjust two y-axis Dear Charles-Edouard Thanks a lot. So no way in R to just simply have one ggplot with to axis as in Excel (attachment)?

This way, the red part of your graph is easier to interpret.
