[R] ggplot - position=position_dodge()) and scale_y_continuous

[Rui Barradas]

Hello,

You must use a categorical variable in 'fill'.

Example: (I also set the fill colours to something else.)


ggplot(data = datax, aes(x = x, y = y, fill = factor(fac))) +
   geom_bar(stat = "identity", color = "black",
            position = position_dodge()) +
   theme_minimal() +
   scale_fill_manual(values = c("blue", "red")) +
   scale_x_continuous(breaks = 1:12) +
   scale_y_discrete(limits = c(0, 100))


Hope this helps,

Rui Barradas
