[英]ggplot2 - How do I add proportion labels to stacked proportion barplot?
I have a grouped stacked proportion barplot that I created like this: 我有一个像这样创建的分组堆叠比例条形图:
df <- data.frame(version = c("Version #1", "Version #2", "Version #1", "Version #2", "Version #1", "Version #2"),
result = c("good", "good", "ok", "ok", "bad", "bad"),
amount = c(1608, 616, 2516, 979, 938, 266))
ggplot(df, aes(x=version,y=amount, fill=result, group = result)) +
geom_bar(stat = "identity", position="fill")
My questions is, how can I add proportion labels to the plot. 我的问题是,如何在情节中添加比例标签。 Something like this:
像这样的东西:
This is straightforward to do with the help of ggstatsplot
package- 这很简单,在
ggstatsplot
的帮助下ggstatsplot
# data
df <- data.frame(version = c("Version #1", "Version #2", "Version #1", "Version #2", "Version #1", "Version #2"),
result = c("good", "good", "ok", "ok", "bad", "bad"),
amount = c(1608, 616, 2516, 979, 938, 266))
# plot
ggstatsplot::ggbarstats(
data = df,
main = result,
condition = version,
counts = amount
) +
ggplot2::ylab("amount")

If you don't want statistical results, just set results.subtitle = FALSE
. 如果您不想要统计结果,只需设置
results.subtitle = FALSE
。
With pipes and usuals: 有管道和通常:
library(tidyverse)
df %>%
group_by(version) %>%
mutate(label = gsub('^[0](\\.\\d{1,2}).*', '\\1', amount / sum(amount))) %>%
ungroup() %>%
ggplot(aes(x = version, y = amount, fill = result, label = label, vjust = 2)) +
geom_col(position = "fill", alpha = .5) +
geom_text(position = 'fill') +
scale_fill_brewer(palette = 'Set1') +
ggthemes::theme_tufte() +
theme(axis.title.x = element_blank(), axis.ticks = element_blank(),
legend.title = element_blank())
