我想用
guides(colour = guide_legend(override.aes = list(size=1)))
在ggplot2()中修改图例图标大小(使其变小)。
它不起作用;我试过换衣服
colour
到
fill
因为这就是我要说的
aes
但这也不管用。
任何帮助都将不胜感激!
# Libraries
library(ggplot2)
# Dataframe
df <- data.frame(location=c("all","all","south","south","north","north"),gender=c("female","male","female","male","female","male"),proportion=c(72.5,27.5,71.3,28.7,75.2,24.8))
# Plot
p_mwe <- ggplot(df, aes(x=location,y=proportion,fill=gender)) +
geom_bar(position="dodge", stat="identity") + theme_classic() + coord_flip()+
scale_fill_manual(values=c("gray88","gray44")) + xlab("")+ ylab("prop (%)") +labs(fill="") +
theme(legend.position="top",legend.text = element_text(colour="black", size=10)) + ggtitle("a) MWE plot") + guides(colour = guide_legend(override.aes = list(size=1)))
