GGPLOT GEOM_ERRORBAR不在酒吧上？

我的数据集看起来像这样：

df<-data.frame(Mean=c(56.0,63.8,46.9,48.5,39.8, 44.4, 51.9, 57.2, 40.5, 40.6),
              sd=c(24.0, 21.8, 24.4, 24.0, 21.0, 19.8, 22.4, 21.5, 20.5, 15.6),
              Quality=as.factor(c("P","M","P","M",
                                  "P","M", "P","M",
                                  "P","M")), 
              Category=c("A","B","C","D","E"),
              Insert= c(0.0, 0.1, 0.3, 0.5, 1.0))

绘图后，我得到以下图： “在此处输入图像说明”

基本上，误差条不在条上，而是在条之间显示。请让我知道如何纠正错误条，以便它们出现在酒吧上。

我使用以下代码：

p <- ggplot(df, aes(x=Category, y=Mean, fill=Quality)) +
  geom_bar(position=position_dodge(), stat="identity",
           colour='black') + 
  geom_errorbar(aes(ymin=Mean-sd, ymax=Mean+sd), width=.2)
print(p)

My dataset looks like this:

df<-data.frame(Mean=c(56.0,63.8,46.9,48.5,39.8, 44.4, 51.9, 57.2, 40.5, 40.6),
              sd=c(24.0, 21.8, 24.4, 24.0, 21.0, 19.8, 22.4, 21.5, 20.5, 15.6),
              Quality=as.factor(c("P","M","P","M",
                                  "P","M", "P","M",
                                  "P","M")), 
              Category=c("A","B","C","D","E"),
              Insert= c(0.0, 0.1, 0.3, 0.5, 1.0))

Upon plotting, I get the following figure:

Basically, the error bars are not on the bars but are presented between the bars. Kindly let me know how can I correct the error bars so that they appear on the bars.

I use the following code:

p <- ggplot(df, aes(x=Category, y=Mean, fill=Quality)) +
  geom_bar(position=position_dodge(), stat="identity",
           colour='black') + 
  geom_errorbar(aes(ymin=Mean-sd, ymax=Mean+sd), width=.2)
print(p)

您还必须使用position_dodge（.9）来躲避错误栏：。

library(ggplot2)

ggplot(df, aes(x=Category, y=Mean, fill=Quality)) +
  geom_bar(position=position_dodge(), stat="identity",
           colour='black') + 
  geom_errorbar(aes(ymin=Mean-sd, ymax=Mean+sd), width=.2, position=position_dodge(.9))

为了达到所需的结果，您还必须使用position = position_dodge（.9），其中.9指的是拒绝条形的默认宽度：

To achieve your desired result you also have to dodge the error bars by using position=position_dodge(.9) where the .9 refers to the default width by which the bars get dodged:

library(ggplot2)

ggplot(df, aes(x=Category, y=Mean, fill=Quality)) +
  geom_bar(position=position_dodge(), stat="identity",
           colour='black') + 
  geom_errorbar(aes(ymin=Mean-sd, ymax=Mean+sd), width=.2, position=position_dodge(.9))
