如何用R创建聚类柱形图？

Question

我有3列数据表-month，p1，p2 我需要显示p1和p2的分组条形图。 x轴为月。 我想知道如何在图表上显示百分比。

Answer 1

您提供的图像称为群集条形图。 您需要重新定义数据集，因为它无法提供群集条形图。

创建数据集：

dt<-data.frame(
  month= c("Jan", "Feb", "Mar", "Apr","May","Jun","Jul","Agu","Sep","Oct","Nov","Dec",
           "Jan", "Feb", "Mar", "Apr","May","Jun","Jul","Agu","Sep","Oct","Nov","Dec"),
  category=c("P1","P1","P1","P1","P1","P1","P1","P1","P1","P1","P1","P1",
             "P2","P2","P2","P2","P2","P2","P2","P2","P2","P2","P2","P2"),
  value=sample(50000:100000,24))

head(dt)

然后绘制

 library(ggplot2)

  ggplot(data=dt, aes(x=month, y=value, fill=category)) +
  geom_bar(stat="identity", position=position_dodge())
