ggplot2 missing aesthetics with dichotomous variable

Edit: I have plotted a likert scale with 15 different categories (Q002_1 - Q002_15) to answer, see graph down below.

What I now want is to plot this graph (code below) as dichotomous variable with ggplot2, see this question for further details.

I get the following error message:

Error: stat_bin requires the following missing aesthetics: x

I know that I do not see the painful obvious here. Can anyone help me out?

Code:

competence_bachelor_dich <- competence_bachelor # dichotomous variable

levels(competence_bachelor_dich) <- list("0" = c("insignificant", "2", "3"),
                         "1" = c("8", "9", "very relevant"))

ggplot(rawdata, aes(x = competence_bachelor_dich)) + 
  geom_histogram() + xlab("") + ylab("Number of participants") + 
  scale_x_discrete(labels = "0", "1") + 
  ggtitle("How do you rate your skills gained with the Bachelor's?") + 
  theme(axis.text.y = element_text(colour = "black"), 
        axis.text.x = element_text(colour = "black")) 

ggsave((filename = "competence_bachelor_dich.pdf"), 
        scale = 1, width = par("din")[1], 
        height = par("din")[2], units = c("in", "cm", "mm"), 
        dpi = 300, limitsize = TRUE)

competence_bachelor_dich is not a column in the rawdata data.frame. If everything eslse is the way it should be your code should work if you add rawdata$competence_bachelor_dich <- competence_bachelor_dich
