[英]Placement of error bars in barplot using ggplot2
嗨,我在RStudio中使用ggplot版本0.9.3.2,我正在嘗試使用錯誤欄制作條形圖。 問題是錯誤欄位置錯誤。 我需要他們在各個酒吧之上。
我有這樣的數據框
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
我有以下代碼
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"))
,並給我這個情節,這是顯而易見的
你應該在ggplot()
調用中移動參數fill=variable
,以確保geom_errorbar()
也使用variable
作為閃避變量。
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"))
