x axis limits for ggplot bar graph in R

Question

How can I set limits on the x axis for a ggplot graph? My code is

    ages <- 6:16
    mu <-  c(0.66849315, 0.55386301,  1.17609589, 0.26111781,  0.466         


        

Answer 1

Use scale_x_continuous rather then scale_x_discrete.

df_GP  + scale_x_continuous(breaks=ages)

If you want to zoom the x labels you can add limits parameter:

 scale_x_continuous(breaks=ages,limits=c(10, 17))
