我有下面的代码,我想改变boxplots的颜色,使它们有相同的填充颜色(灰色)。我想改变boxplots的颜色,使它们具有相同的填充颜色(灰色).另外,我想让stat_summary文本贴在每个barplot的底部,但vjust似乎只提供相对位置?
我想把统计_摘要文本贴在每个条形图的底部,但vjust似乎只提供相对位置?
boxp <- ggplot(mtcars, aes(as.factor(cyl), wt, fill=as.factor(am)) ) +
geom_bar(position = "dodge", stat = "summary", fun.y = "median") +
geom_boxplot(outlier.shape = NA, width=0.2, color = "black", position = position_dodge(0.9)) +
stat_summary(aes(label=round(..y..,2)), fun.y=median, geom="text", size=8, col = "white", vjust=8, position = position_dodge(0.9)) +
stat_summary(fun.y=mean, geom="point", shape=18, size=4, col="white", position = position_dodge(0.9)) +
labs(x = "Conditions", y = "Medians") +
scale_y_continuous(limits=c(0,7),oob = rescale_none) +
theme_bw()
boxp
这里有一个可能的解决方案,但它需要ggplot v3.3.0的版本。stage()
职能。
要指出主要的变化。
fill = 'gray'
stage()
来计算统计量,但却用 0
作为实际安置。library(ggplot2)
library(scales)
ggplot(mtcars, aes(as.factor(cyl), wt,
group = interaction(as.factor(cyl), as.factor(am)))) +
geom_bar(aes(fill=as.factor(am)), position = "dodge", stat = "summary", fun = "median") +
geom_boxplot(outlier.shape = NA, width=0.2,
color = "black", fill = 'gray',
position = position_dodge(0.9)) +
stat_summary(aes(label=round(after_stat(y), 2), y = stage(wt, after_stat = 0)),
fun=median, geom="text", size=8, col = "white", vjust=-0.5,
position = position_dodge(0.9)) +
stat_summary(fun=mean, geom="point", shape=18, size=4, col="white", position = position_dodge(0.9)) +
labs(x = "Conditions", y = "Medians") +
scale_y_continuous(limits=c(0,7),oob = rescale_none) +
theme_bw()
