创建堆叠条形图,其中每个堆叠的总和为 100% [英] Create stacked barplot where each stack is scaled to sum to 100%
问题描述
我有一个像这样的 data.frame:
I have a data.frame like this:
df <- read.csv(text = "ONE,TWO,THREE
23,234,324
34,534,12
56,324,124
34,234,124
123,534,654")
我想生成一个看起来像这样的百分比条形图(在 LibreOffice Calc 中制作):
I want to produce a percent bar plot which looks like this (made in LibreOffice Calc):
因此,应该对条形进行标准化,以便所有堆栈具有相同的高度并且总和为 100%.到目前为止,我所能得到的只是一个堆积的条形图(不是百分比),使用:
Thus, the bars should be standarized so all stacks have the same height and sums to 100%. So far all I have been able to get is is a stacked barplot (not percent), using:
barplot(as.matrix(df))
有什么帮助吗?
推荐答案
这是一个使用 ggplot
包(版本 3.x)的解决方案,以及您目前获得的解决方案.
Here's a solution using that ggplot
package (version 3.x) in addition to what you've gotten so far.

我们使用 geom_bar
的 position
参数设置为 position = "fill"
.如果您想使用 position_fill()
的参数(vjust
和 reverse代码>).
We use the position
argument of geom_bar
set to position = "fill"
. You may also use position = position_fill()
if you want to use the arguments of position_fill()
(vjust
and reverse
).
请注意,您的数据采用宽"格式,而 ggplot2
要求它采用长"格式.因此,我们首先需要收集
数据.
Note that your data is in a 'wide' format, whereas ggplot2
requires it to be in a 'long' format. Thus, we first need to gather
the data.
library(ggplot2)
library(dplyr)
library(tidyr)
dat <- read.table(text = " ONE TWO THREE
1 23 234 324
2 34 534 12
3 56 324 124
4 34 234 124
5 123 534 654",sep = "",header = TRUE)
# Add an id variable for the filled regions and reshape
datm <- dat %>%
mutate(ind = factor(row_number())) %>%
gather(variable, value, -ind)
ggplot(datm, aes(x = variable, y = value, fill = ind)) +
geom_bar(position = "fill",stat = "identity") +
# or:
# geom_bar(position = position_fill(), stat = "identity")
scale_y_continuous(labels = scales::percent_format())
