ggplot geom_bar - 酒吧太宽 [英] ggplot geom_bar - bars too wide

问题描述

对于非信息性标题，我感到抱歉。

 > y = read.csv（textConnection（scan（，sep =\\\
，what =raw）））
，org，art，type，length 
191，gk，Finish，short，4 
147，ik，参加，短，7 
175 ，gl，Finish，long，11 
192，il，Attending，long，95 
144，gm ，之间，5 
161，im，参加，之间，15 
164，tu，Something，young，8 
190，tv，Something，old，4 
 
>解压缩=函数（x）x [rep（1：nrow（x），x $ length）， -  ncol（x）] 
> exstatus =解压缩（y）
  

然后剧情

  ggplot（exstatus，aes（x = type，fill = art））+ 
 geom_bar（aes（y = .. count ../ sum（.. count ..）），position =dodge）
  

问题在于两个最右边的条（年轻，老）太厚 - 东西占据了整个宽度 - 这不是我想要的。

对不起，我无法更好地解释它。

解决方案

使用facet_grid而不是position =dodge

  ggplot（exstatus，aes（x = art，fill = art））+ 
 geom_bar（aes（y = .. count ../ sum（.. count ..））） + 
 facet_grid（〜type，scales =free，space =free）

I am sorry for the non-informative title.

> y=read.csv(textConnection(scan("",sep="\n",what="raw")))
"","org","art","type","length"
"191","gk","Finish","short",4
"147","ik","Attending","short",7
"175","gl","Finish","long",11
"192","il","Attending","long",95
"144","gm","Finish","between",5
"161","im","Attending","between",15
"164","tu","Something","young",8
"190","tv","Something","old",4

> decompress=function(x)x[rep(1:nrow(x),x$length),-ncol(x)]
> exstatus=decompress(y)

and then the plot

ggplot(exstatus, aes(x=type, fill=art))+
geom_bar(aes(y=..count../sum(..count..)),position="dodge")

The problem is that the two rightmost bars ("young", "old") are too thick - "something" takes up the whole width - which is not what I intended.

I am sorry that I can not explain it better.

解决方案

Use facet_grid instead of position="dodge"

  ggplot(exstatus, aes(x=art, fill=art))+
  geom_bar(aes(y=..count../sum(..count..))) + 
  facet_grid(~type,scales="free",space="free")
