ggplot2中的水平Barplot [英] Horizontal Barplot in ggplot2

问题描述

我正在制作 ggplot2 中的水平点图（？），这让我想到要创建一个水平barplot。然而，我发现可以做到这一点的一些限制。

以下是我的数据：

<$ p $ （Ad，Rt，Ra，Mo，Ao，Do），
Avg_Cost = c（5.30,3.72,2.91,2.64,1.17,1.10），Num = c（6：1））
df
str（df）

最初，我使用以下代码生成了一个点图：

  require（ggplot2）
 ggplot（df，aes（x = Avg_Cost，y = reorder（Seller，Num）））+ 
 geom_point（color =black，fill =lightgreen） + 
 opts（title =Avg Cost）+ 
 ylab（Region）+ xlab（）+ ylab（）+ xlim（c（0,7））+ 
 opts（axis.text.y = theme_text（family =sans，face =bold，size = 12））+ 
 opts（axis.text.x = theme_text（family =sans，face =bold，size = 12））
  

但是，我正在尝试创建一个横向barplot，并发现我无法这样做。我试过 coord_flip（），但这也没有帮助。

  ggplot（df，aes（x = Avg_Cost，y = reorder（Seller，Num）））+ 
 geom_bar（color =black，fill =lightgreen）+ 
 opts（title =平均成本）+ 
 ylab（Region）+ xlab（）+ ylab（）+ xlim（c（0,7））+ 
 opts（plot.title = theme_text ）+ 
 opts（axis.text.y = theme_text（family =sans，face =bold，size = 12））+ 
 opts（ axis.text.x = theme_text（family =sans，face =bold，size = 12））
  

任何人都可以为如何在 ggplot2 中生成水平barplot提供一些帮助吗？

解决方案

  ggplot（df，aes（x = reorder（Seller，Num），y = Avg_Cost））+ 
 geom_bar（stat ='identity'）+ 
 coord_flip（）
  

没有 stat ='identity' code> ggplot希望将您的数据汇总到计数中。

I was working on doing a horizontal dot plot (?) in ggplot2, and it got me thinking about trying to create a horizontal barplot. However, I am finding some limitations in being able to do this.

Here is my data:

df <- data.frame(Seller=c("Ad","Rt","Ra","Mo","Ao","Do"), 
                Avg_Cost=c(5.30,3.72,2.91,2.64,1.17,1.10), Num=c(6:1))
df
str(df)

Initially, I generated a dot plot using the following code:

require(ggplot2)
ggplot(df, aes(x=Avg_Cost, y=reorder(Seller,Num))) + 
    geom_point(colour="black",fill="lightgreen") + 
    opts(title="Avg Cost") +
    ylab("Region") + xlab("") + ylab("") + xlim(c(0,7)) +
    opts(plot.title = theme_text(face = "bold", size=15)) +
    opts(axis.text.y = theme_text(family = "sans", face = "bold", size = 12)) +
    opts(axis.text.x = theme_text(family = "sans", face = "bold", size = 12))

However, I am now trying to create a horizontal barplot and finding that I am unable to do so. I've tried coord_flip() and that was not helpful either.

ggplot(df, aes(x=Avg_Cost, y=reorder(Seller,Num))) + 
    geom_bar(colour="black",fill="lightgreen") + 
    opts(title="Avg Cost") +
    ylab("Region") + xlab("") + ylab("") + xlim(c(0,7)) +
    opts(plot.title = theme_text(face = "bold", size=15)) +
    opts(axis.text.y = theme_text(family = "sans", face = "bold", size = 12)) +
    opts(axis.text.x = theme_text(family = "sans", face = "bold", size = 12)) 

Can anyone provide some assistance on how to generate a horizontal barplot in ggplot2?

解决方案

ggplot(df, aes(x=reorder(Seller, Num), y=Avg_Cost)) +
  geom_bar(stat='identity') +
  coord_flip()

Without stat='identity' ggplot wants to aggregate your data into counts.
