当我绘制具有相同颜色的点和文本时,a图例中的形状和形状重叠.
我可以告诉ggplot不要a在图例中画出来吗?怎么样?
M <- data.frame(t=letters[1:16],
xx=runif(16),
yy=runif(16),
g=rep(c("A","B","C","D"),4))
str(M)
ggplot(M,aes(x=xx,y=yy,label=t,colour=g)) +
geom_point(shape=3) +
geom_text(vjust=0,hjust=0) +
scale_colour_discrete()

只需添加show_guide = F您的geom_text:
ggplot(M,aes(x=xx,y=yy,label=t,colour=g)) +
geom_point(shape=3) +
geom_text(vjust=0,hjust=0, show_guide = F) +
scale_colour_discrete()
