Question

我有这个情节

 dummy = data.frame(group=c("A","B","C","D","E","F","G","H","I","J"),
           y = c(80,75,68,62,75,71,73,69,60,78),
           x=c(30, 32,36,34,28,41,35,29,22,33),
           size =c(8,5,7,2,3,2,4,6,9,10)
           )

ggplot(dummy,aes(x=x,y=y,color=group, size = size)) + 
  geom_point()

我不希望出现尺寸图例的文字。所以我不希望2,4,6,8 10出现在大小图例中。我仍然想要圆圈和尺寸。

我怎样才能实现这一目标？

谢谢。

?guides和?guide_legend中有很多有用的信息：

ggplot(dummy,aes(x=x,y=y,color=group, size = size)) + 
  geom_point() +
  guides(size = guide_legend(label.theme = element_blank()))

2个图例，但只显示一个文本
