问题描述
您好,我在RStudio中使用ggplot版本0.9.3.2,我正在尝试使用错误栏制作条形图。问题是错误栏位置错误。我需要他们去个别酒吧。
我有这样的数据框
浓度变量值sd
1 0 AF_B 0.3567126 0.010391001
2 0.5x AF_B 0.3355766 0.003480245
3 1x AF_B 0.3001138 0.009104821
4 5x AF_B 0.2658911 0.016312390
5 10x AF_B 0.2115522 0.011056590
6 100x AF_B 0.2655958 0.015092367
7 0 D_B 0.3567126 0.010391001
8 0.5x D_B 0.3453078 0.011639252
9 1x D_B 0.3380180 0.004357810
10 5x D_B 0.3349004 0.018119644
11 10x D_B 0.3186451 0.014515436
12 100x D_B 0.3174700 0.016685932
我有以下代码:
$ b $ pre $ dodge = position_dodge(width = 0.9)
c = ggplot(data = dm,aes (y =值,x =浓度))
c + geom_bar(position = dodge,
stat =identity,
aes(fill = variable,color = variable,group = variable,color =black))+
geom_errorbar( aes(ymin = value-sd,ymax = value + sd),
position = dodge,
width = 0.1,
size = 0.3)+
ylab(mu_max [h -1)])+
scale_x_discrete(limits = c(0,0.5x,1x,5x,10x,100x))
,并且给我这个图,这很明显是
您应该在 ggplot()
调用中移动参数 fill = variable
,以确保 geom_errorbar()
也使用变量
作为躲避变量。
ggplot(data = dm,aes(y = value,x = concentration,fill = variable))+
geom_bar(position = position_dodge(),
stat =identity)+
geom_errorbar(ae s(ymin = value-sd,ymax = value + sd),
position = dodge,width = 0.1,size = 0.3)+
ylab(mu_max [h-1])+
scale_x_discrete(limits = c(0,0.5x,1x,5x,10x,100x))
Hi i am using ggplot version 0.9.3.2 in RStudio and I am trying to make a bar plot with error bars. The problem is that the error bars are positioned wrong. I need them to go on top of the individual bars.
I have a data frame like this
concentration variable value sd
1 0 AF_B 0.3567126 0.010391001
2 0.5x AF_B 0.3355766 0.003480245
3 1x AF_B 0.3001138 0.009104821
4 5x AF_B 0.2658911 0.016312390
5 10x AF_B 0.2115522 0.011056590
6 100x AF_B 0.2655958 0.015092367
7 0 D_B 0.3567126 0.010391001
8 0.5x D_B 0.3453078 0.011639252
9 1x D_B 0.3380180 0.004357810
10 5x D_B 0.3349004 0.018119644
11 10x D_B 0.3186451 0.014515436
12 100x D_B 0.3174700 0.016685932
I have the following code
dodge = position_dodge(width=0.9)
c = ggplot(data=dm, aes(y=value,x=concentration))
c + geom_bar(position = dodge,
stat="identity",
aes(fill=variable,colour=variable,group=variable, colour="black")) +
geom_errorbar(aes(ymin=value-sd,ymax=value+sd),
position=dodge,
width=0.1,
size=0.3) +
ylab("mu_max [h-1]") +
scale_x_discrete(limits=c("0","0.5x","1x","5x","10x","100x"))
, and gives me this plot, which is clearly

You should move the argument fill=variable
inside the ggplot()
call to ensure that geom_errorbar()
also use variable
as the dodging variable.
ggplot(data=dm,aes(y=value,x=concentration,fill=variable))+
geom_bar(position = position_dodge(),
stat="identity") +
geom_errorbar(aes(ymin=value-sd,ymax=value+sd),
position=dodge,width=0.1,size=0.3)+
ylab("mu_max [h-1]") +
scale_x_discrete(limits=c("0","0.5x","1x","5x","10x","100x"))
