订购位置“道奇"在ggplot2中 [英] Ordering position "dodge" in ggplot2

问题描述

看起来很简单，但是我找不到解决方法.

Seems simple but i couldnt find a solution.

names(AllCoursesReg)
[1] "name"   "Course" "Status"

我的代码

ggplot(AllCoursesReg, aes(Course, fill = Status)) + 
geom_bar(aes(order = Status), position = "dodge", colour = "black") + theme_bw()+
guides(fill = guide_legend(reverse = TRUE)) 

我只希望注册人位于左侧而不是右侧. 我已经尝试过订单，水平，因素，但它不起作用

I just want the Registrants to be on the left not on the right. I have tried Order, level, factor, and it is not working

感谢您的帮助.

推荐答案

您必须确定factor的级别顺序.这是来自?geom_bar的示例.

You have to decide on the ordering of the levels of a factor. Here's an example from ?geom_bar.

# example from ?geom_bar
ggplot(diamonds, aes(clarity, fill=cut)) + geom_bar(position="dodge")
# reorder cut using levels = rev(levels(cut))
ggplot(diamonds, aes(clarity, fill=factor(cut, levels = rev(levels(cut))))) + 
  geom_bar(position="dodge") + 
  scale_fill_discrete('cut') # change name back to cut
