[英]percentage plot using ggplot2
I would like to plot something like the image below but I have an error of "stat_count() can only have an x or y aesthetic.".我想 plot 类似于下图,但我有一个错误“stat_count() 只能有 x 或 y 美学。”。 So I change it to stat="identity".
所以我把它改成stat="identity"。 But the outcome is not the same as the example I found online.
但是结果和我在网上找到的例子不一样。
Example found online:网上找的例子:
example is found from: https://sebastiansauer.github.io/percentage_plot_ggplot2_V2/示例来自: https://sebastiansauer.github.io/percentage_plot_ggplot2_V2/
My code我的代码
geom_bar(aes(y=pct_change, fill=factor(Year)), stat="count")+
geom_text(aes( label = scales::percent(pct_change),
y= pct_change ), stat= "count", vjust = -.5) +
ylab("Avg Unit Price") +
facet_grid(~Type.of.Sale) +
scale_y_continuous(labels = scales::percent)
Here is an example with the mtcars
dataset how you could achieve your task:这是
mtcars
数据集的示例,您可以如何完成任务:
library(tidyverse)
ggplot(mtcars, aes(x = cyl, group=am))+
geom_bar(aes(y=..prop.., fill=factor(..x..)), stat="count")+
geom_text(aes( label = scales::percent(..prop..),
y= ..prop..), stat= "count", vjust = -.5) +
ylab("Avg Unit Price") +
facet_grid(~am) +
scale_y_continuous(labels = scales::percent)
