在R中反向显示标签的堆积的条形图

Question

我正在尝试创建一个堆积条形图，条形图中间有标签。 由于某种原因，标签被放置在第二列（“eIC”）的错误位置。

这是代码：

Role.Type=c("Other", "eIC", "eIC", "Manager", "eIC", "eIC", "Design", "eIC", "eIC", "Other", "Product", "Other", "Manager", "eIC", "eIC")
Role=c('Agile Coach', 'Android', 'Backend', 'Eng Manager', 'Data', 'Data Scientist', 'Design', 'iOS', 'ML', 'Operations', 'Product', 'Quality', 'Director', 'User Research', 'Web')
People=c(3, 3, 20, 11, 10, 7, 2, 2, 21, 1, 11, 3, 2, 2, 5)
df <- data.frame(Role.Type, Role, People)

g <- ggplot(df, aes(Role.Type, People)) +
       geom_col(aes(fill=Role), position='stack') +
       geom_text(aes(label=Role), size=3, position=position_stack(vjust=.5)) +
       scale_y_continuous(breaks=seq(0, 100, by=10)) +
       labs(title="Team Role Breakdown", y="People", x="Role Type")
g

结果

Answer 1

你只需要在第一个ggplot（）函数中加上“fill = Role”。 这样就可以将文本标签放在正确的位置：

g <- ggplot(df, aes(Role.Type, People, fill = Role)) +
  geom_col(position='stack') + 
  geom_text(aes(label=Role), size=3, position=position_stack(vjust=.5)) +
  scale_y_continuous(breaks=seq(0, 100, by=10)) + 
  labs(title="Team Role Breakdown", y="People", x="Role Type")
