I have created a histogram plot using the following code:

  p<-ggplot(df, aes(x=value))  
    geom_histogram(color="black", fill="white", binwidth=5)
  
  p

My data ranges between 0 and 17. What are the bands of the bins e.g. is the 0 section 0-4? Is there a way of altering where the bands begin?

CodePudding user response：

You can tell ggplot where you want one of the bins to be centered. For example, if you want bins between 0, 5, 10, etc you would do:

ggplot(df, aes(x = value))  
  geom_histogram(color = "black", fill = "white", binwidth = 5, center = 2.5) 

Data

set.seed(1)
df <- data.frame(value = rpois(25000, 7))
