尽管我的查询以降序显示值,但ggplot然后按字母顺序显示它们,而不是以升序显示。
该问题的已知解决方案似乎无效。他们建议对值使用Reorder或factor,在这种情况下不起作用
这是我的代码:
boxoffice %>%
group_by(studio) %>%
summarise(movies_made = n()) %>%
arrange(desc(movies_made)) %>%
top_n(10) %>%
arrange(desc(movies_made)) %>%
ggplot(aes(x = studio, y = movies_made, fill = studio, label = as.character(movies_made))) +
geom_bar(stat = 'identity') +
geom_label(label.size = 1, size = 5, color = "white") +
theme(legend.position = "none") +
ylab("Movies Made") +
xlab("Studio")
答案 0 :(得分:1)
对于那些想要更完整示例的人,这是我得到的地方:
library(dplyr)
library(ggplot2)
# get some dummy data
boxoffice = boxoffice::boxoffice(dates=as.Date("2017-1-1"))
df <- (
boxoffice %>%
group_by(distributor) %>%
summarise(movies_made = n()) %>%
mutate(studio=reorder(distributor, -movies_made)) %>%
top_n(10))
ggplot(df, aes(x=distributor, y=movies_made)) + geom_col()

您需要将boxoffice$studio
转换为有序因子。然后 ggplot 将遵守数据集中的行顺序,而不是按字母顺序排列。您的dplyr链将如下所示:
boxoffice %>%
group_by(studio) %>%
summarise(movies_made = n()) %>%
arrange(desc(movies_made)) %>%
ungroup() %>% # ungroup
mutate(studio = factor(studio, studio, ordered = T)) %>% # convert variable
top_n(10) %>%
arrange(desc(movies_made)) %>%
ggplot(aes(x = studio, y... (rest of plotting code)
