错误条现在不在位置。
我尝试使用ggplot定位它们:
ggplot(d.Mean, aes(x=Treatment, y=Flux.m, fill=Plant)) +
geom_bar(size=4, stat="identity", position="stack") +
geom_errorbar(aes(ymin=Flux.m - Flux.se, ymax=Flux.m + Flux.se),
width=.2, stat="identity") +
guides(fill=FALSE) +
labs(x="Treatment", y="N uptake %") +
mytheme +
theme(legend.text = element_text(size=15)) +
guides(fill=FALSE) +
scale_fill_grey()
我的数据
Treatment Plant Flux.m Flux.se
NC Weed 1.1907929 0.162910442
NC Wheat 0.2198656 0.009046636
NF Weed 0.5080035 0.116434029
NF Wheat 0.6842919 0.073096108
TC Weed 0.1323349 0.024147990
TC Wheat 0.2239926 0.075459460
TF Weed 0.1435406 0.019167675
TF Wheat 0.5904143 0.066450625
现在,它不在位置上。我想把它放在酒吧上面。
答案 0 :(得分:2)
geom_errorbar
不知道您的geom_bar
层中的堆栈,因此您需要添加一个帮助程序列以告诉它从哪里开始,以y开头:
d.Mean %>%
group_by(Treatment) %>%
arrange(Treatment, desc(Plant)) %>%
mutate(Flux.m_cuml = cumsum(Flux.m)) %>%
ggplot(aes(x=Treatment,y=Flux.m,fill=Plant))+
geom_bar(size=4,stat="identity",position="stack")+
geom_errorbar(aes(ymin=Flux.m_cuml - Flux.se, ymax=Flux.m_cuml + Flux.se),
width=.2, stat="identity")+
guides(fill=FALSE)+
scale_fill_grey() +
labs(x="Treatment",y="N uptake %")+
#mytheme+
theme(legend.text = element_text(size=15))
