Question

我正在使用ggplot绘制数据框。

数据框是这样的：

   cluster      Profession        means
1        1   Bank_Employee 4.151786e-02
2        2   Bank_Employee 1.150637e-02

34       2       OtherProf 1.510760e-02

命令如下：

ggplot(data=dfcards13ml, aes(x=Profession, y=means, fill= cluster)) +
  geom_bar(stat="identity", position=position_dodge())+
  labs(title="Proportions of Professions in each Cluster",
       x="Professions", y = "Mean")

输出是这样的：

Barplot

正如你所看到的那样，条形图是叠加的，虽然我已经在代码中规定要躲避＆＃39;。

你可以解释一下吗？我应该在代码中更改什么？

您的建议将不胜感激。

Answer 1

您需要指定组映射：

ggplot(data=dfcards13ml, 
       aes(x=Profession, y=means, fill= cluster, group = cluster)) + 
geom_bar(stat="identity", position=position_dodge()) +
labs(title="Proportions of Professions in each Cluster", 
     x="Professions", y = "Mean")

ggplot中的Barplot不符合命令＆＃39; position = position_dodge（）＆＃39;
