将y轴转换为百分比ggplot [英] transform y axis to percents ggplot

问题描述

我已经使用堆叠条形图（与coord_flip）来比较前后测试对照组和治疗组的分布（这是我正在玩的几种技术之一）。这里是情节：

这里是代码（对不起，没有数据集是不可重现的。如果这是一个问题，我会组成一个可重复的数据集，因为我不能共享真实数据）：

  m4 < -  ggplot（data = v，aes（x = trt，fill = value）） 
 m5 < -  m4 + geom_bar（）+ coord_flip（）+ 
 facet_grid（time_type）+ scale_fill_grey（）
  

如何将y轴（实际上是在底部会费到 coord_flip ）上更改为百分比，以便每条线都相等长度？所以我希望能够成为百分之百。我需要某种转变，我敢打赌，ggplot已经或可以很容易地创建并应用一些方法。

只需 position_fill ，方法是设置

  + geom_bar（position =fill）
  

I have used a stacked bar chart (with coord_flip) to try to compare distributions (this is one a several techniques I'm playing with) for a control and treatment group for pre and post test. Here is the plot:

and here is the code (Sorry it's not reproducible with no data set. If this is a problem I'll make up a reproducible data set as I can't share the real data):

m4 <- ggplot(data=v, aes(x=trt, fill=value))
m5 <- m4 +  geom_bar() + coord_flip() + 
      facet_grid(time~type) + scale_fill_grey()

How can I change the y axis (which is actually on the bottom dues to coord_flip) to percents so every bar is equal in length? So I want counts to become percents. I need some sort of transformation that I'm betting ggplot has or could easily be created and applied some how.

解决方案

You probably just want position_fill, by setting,

+ geom_bar(position = "fill")
