我正在将数据点叠加在箱形图上。我遇到的问题是尝试标记数据点时,标签未显示在数据点上。感谢您的帮助。谢谢
df <- data.frame(sno= c(1:10), A =sample(1:1000, 10), B=sample(1:100, 10), C=sample(1:300, 10))
df <- melt(df, id.vars = "sno")
library(ggplot2)
ggplot(df, aes(x="", y=value, label=sno)) +
facet_wrap(~variable, scales = "free") +
geom_boxplot()+
geom_jitter(position=position_jitter(0.2), col="blue") +
geom_text(aes(label=sno))
答案 0 :(得分:2)
您可以使用jitter
中的base
来创建自己的数据集,然后在geom_point
中使用它。使用这种方法,您可以将x
分配给geom_label
,以便对齐点和标签。
df <- data.frame(sno= c(1:10), A =sample(1:1000, 10),
B=sample(1:100, 10), C=sample(1:300, 10))
df <- reshape2::melt(df, id.vars = "sno")
dfj <- df
dfj$xj <- jitter(as.numeric(factor(df$variable)))
library(ggplot2)
ggplot(df, aes(x=as.numeric(variable), y=value, group=NULL)) +
facet_wrap(~variable, scales = "free") +
geom_boxplot()+
geom_point(data = dfj, aes(x=xj), col="blue") +
geom_text(data = dfj, aes(x=xj,label=sno, hjust=2)) +
scale_x_continuous(breaks = as.numeric(df$variable))+
theme(axis.title.x=element_blank(),
axis.text.x=element_blank(),
axis.ticks.x=element_blank())
#> Warning: Continuous x aesthetic -- did you forget aes(group=...)?
