在ggplot中,可以使用geom_text()函数来添加文本标签到piechart的外部。 具体步骤如下: 导入ggplot包:在R中使用library(ggplot2)命令导入ggplot包。 准备数据:准备一个包含分类和对应数值的数据集。 创建饼图:使用ggplot()函数创建一个基础的饼图对象,并设置数据集和分类变量。 添加饼图层:使用geom_bar()函数添加...
Pie charts are the classic choice for showing proportions for mutually-exclusive categories. We'll show you how to use ggplot2 package to create a basic pie chart in R.
It’s better now, just need to add labels directly on chart. # Load ggplot2 library(ggplot2) # Create Data data <- data.frame( group=LETTERS[1:5], value=c(13,7,9,21,2) ) # Basic piechart ggplot(data, aes(x="", y=value, fill=group)) + geom_bar(stat="identity", width=...
library(ggplot2) # Barplot bp<- ggplot(df, aes(x="", y=value, fill=group))+ geom_bar(width = 1, stat = "identity") bp Create a pie chart : pie <- bp + coord_polar("y", start=0) pie Change the pie chart fill colors ...
If you need to display the values of your pie chart outside for styling or because the labels doesn’t fit inside the slices you can use the geom_label_repel function of the ggrepel package after transforming the original data frame as in the example below. # install.packages("ggplot2")...
PieGlyph是基于ggplot2的一个扩展 R 包,旨在绘制饼形散点图,以显示不同的类别组成。 加载包 library(tidyverse) library(PieGlyph) 构建数据集 set.seed(123) plot_data <- data.frame(response = rnorm(30, 100, 30), system = 1:30, group = sample(size = 30, x = c('G1', 'G2', 'G3'...
