可能重复:
Create a bar graph with pre-summarized data using ggplot2

我们可以看到使用提供的钻石数据可以很容易地叠加条形图。
但是,我尝试使用的数据集与钻石数据不同,因为我已经对其进行了总结。
附件是我的意思的最小例子
AgeGroup gender Level.of.Education status count
1 18-25 male High School married 10
2 18-25 male High School single 20
3 18-25 male College married 25
4 18-25 male College single 10
5 18-25 male PhD married 50
6 18-25 male PhD single 4
7 18-25 male GED married 20
8 18-25 male GED single 100
9 18-25 female High School married 20
10 18-25 female High School single 10
11 18-25 female College married 30
12 18-25 female College single 60
13 18-25 female PhD married 80
14 18-25 female PhD single 10
15 18-25 female GED married 5
16 18-25 female GED single 2
完整的数据集也有时间表,所以我想要制作的是一个堆积的条形图,显示已婚人数和未婚人数加班,使用“教育水平”作为条形填充。
完整数据集太大,以至于非常需要像这样的聚合数据。
您的意见对我很有帮助。感谢。

您需要stat='identity'
。
ggplot(dat, aes(x=status, y=count, fill=Level.of.Education)) +
geom_bar(stat='identity')
我还建议按性别分面:
ggplot(dat, aes(x=status, y=count, fill=Level.of.Education)) +
geom_bar(stat='identity') +
facet_wrap(~gender)
