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:
ggplot2 是一个用于创建统计图形的强大 R 语言包。在 ggplot2 中,饼图(pie chart)通常是通过 geom_bar() 函数并设置 position = "fill" 来实现的,因为 ggplot2 并没有直接创建饼图的函数。要在饼图中正确放置标签,可以使用 ggplot2 的geom_text() 函数结合 position_stack() 或position_fill()。 以下是...

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.
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(),...
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...

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")) ...
【2.5.2】饼形图(Pie Chart) 饼图是显示群组成的经典方式。 然而,现在通常不建议使用它,因为馅饼部分的面积有时会变得误导。 因此,如果您要使用饼图,强烈建议明确记下饼图每个部分的百分比或数字。 # Import df_raw = pd.read_csv("https://github.com/selva86/datasets/raw/master/mpg_ggplot2.csv")...
