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:
Create the pie chart of the count of observations in each group : ggplot(PlantGrowth, aes(x=factor(1), fill=group))+ geom_bar(width = 1)+ coord_polar("y") Customized pie charts Create a blank theme : blank_theme <- theme_minimal()+ theme( axis.title.x = element_blank(),...
> pie <- ggplot(df, aes(x = "", y=freq, fill = factor(class))) + + geom_bar(width = 1, stat = "identity") + + theme(axis.line = element_blank(), + plot.title = element_text(hjust=0.5)) + + labs(fill="class", + x=NULL, + y=NULL, + title="Pie Chart of class"...
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.

Te function pie3D()[in plotrix package] can be used to draw a 3D pie chart. Install plotrix package: install.packages("plotrix") Use pie3D(): # 3D pie chart library("plotrix") pie3D(df$value, labels = df$group, radius = 1.5, col = c("#999999", "#E69F00", "#56B4E9")) ...
Here x is a vector containing the numeric values present in the pie chart, such as those production figures in the above example. Labels take a name for those values in X, such as the name of chemicals. The radius argument is for the radius of the circle of the pie chart. Its typical...
