Geom_dotplot，y 轴显示计数

Question

I'm trying to plot a dotplot using geom_dotplot in which each dot represents an observation of my data set. Therefore, the y-axis shouldn't represent density but actual counts. I'm aware of this thread which revolves around the same topic. However, I haven't managed to solve my issue following the same methodology.

df <- data.frame(x = sample(1:500, size = 150, replace = TRUE))

ggplot(df, aes(x)) +
  geom_dotplot(method = 'histodot', binwidth = 1)

And I obtain the following graph , I want to obtain one similar to this one where I can manipulate dots' size, space between, etc.

Thanks in advance

Answer 1

You can modify the binwidth argument to cause the points to stack. For example,

df %>%
  ggplot(aes(x = x)) +
  geom_dotplot(method = "histodot", binwidth = 20)

There is a dotsize argument that can be used to modify the size of the dot.
