我正在尝试使用plotly的这个示例绘制两条垂直线来表示均值和中位数。
可重现代码
library(plotly)
# data
df1 <- data.frame(cond = factor( rep(c("A","B"), each=200) ),
rating = c(rnorm(200),rnorm(200, mean=.8)))
df2 <- data.frame(x=c(.5,1),cond=factor(c("A","B")))
# graph
ggplot(data=df1, aes(x=rating, fill=cond)) +
geom_vline(aes(xintercept=mean(rating, na.rm=T))
, color="red", linetype="dashed", size=1, name="average") +
geom_vline(aes(xintercept=median(rating, na.rm=T))
, color="blue", linetype="dashed", size=1, name="median") +
geom_histogram(binwidth=.5, position="dodge")
ggplotly()
问题
我想要隐藏显示在红色文本“average”旁边的y值-2.2。但是,我希望文本“average”像下面截图中一样显示。也就是说,我只想要隐藏我用黑色叉号标记的标签。 同样的问题也适用于中位数线。
我的尝试失败了
#plot
gg <- ggplot(data=df1, aes(x=rating, fill=cond)) +
geom_vline(aes(xintercept=mean(rating, na.rm=T))
, color="red", linetype="dashed", size=1, name="average")+
geom_vline(aes(xintercept=median(rating, na.rm=T))
, color="blue", linetype="dashed", size=1, name="median") +
geom_histogram(binwidth=.5, position="dodge")
p <- plotly_build(gg)
# p$data[[1]]$y[1:2] <- " " # another attempt, but the line doesn't display at all
p$data[[1]]$y <- NULL # delete the y-values assigned to the average line
plotly_build(p)
这次尝试仍然显示为
0
(如下图所示):
