ggplot中的geom_point（scale_colour_manual）中的填充和边框颜色

问题描述

我使用ggplot做一个散点图。我想要有一个特定的颜色和填充点（在情节， color =blue，fill =cyan4，例如），但我不能找到如何。这一点是：

I'm doing an scatter plot using ggplot. I would like to have points with a particular colour and fill (in plot, colour="blue", fill="cyan4", for ex.) but I can't find how. What I have to this point is:

ggplot(df, aes(own,method)) +
  panel.configuration +
  scale_shape_identity() +  #to use the 'plot' shape format.
  geom_point(aes(color = factor(label)), position = "jitter",size=3) +  

b $ b

（在之前的 geom_point 中，我尝试添加 shape = 21 c $ c> plot ）

(In previous geom_pointI tried adding shape=21 as I would have done in plot)

  scale_colour_manual(values=c("A"="chocolate3","B"="cyan4")) +
  scale_fill_manual(values=c("A"="green", "B"="red")) + #DOES NOTHING...
  xlim(7,47) + ylim(7,47)+ ... etc.

我得到没有shape = 21

This is what i get without "shape=21"

这是我添加shape = 21时得到的。在这两种情况下，它忽略 scale_fill

This is what I get when I add "shape=21". In both cases it ignores scale_fill

我也试过在geom_point中添加 fill = c（blue，red）但R抱怨：错误：不兼容长度为集美观：形状，大小，填充。

I also tried adding fill=c("blue","red") in geom_point, but R complains: "Error: Incompatible lengths for set aesthetics: shape, size, fill".

有关如何取得建议吗？在我的代码中 scale_fill 有什么问题？

Any suggestions about how to get it? What is wrong with scale_fill in my code?

非常感谢！

资料（df）如下：

21 15 A
24 16 A
24 17 A
28 14 A
24 15 A
22 15 A
20 18 A
24 18 A
34 9 B
38 12 B
41 19 B
42 13 B
36 12 B
40 17 B
41 14 B
37 12 B
40 13 B
37 15 B
35 15 B

推荐答案

您必须使用 21 25 。这些是颜色和填充属性：

You'll have to use shapes from 21 to 25. These are the ones that have colour and fill properties:

ggplot(df, aes(own, method)) + 
     geom_point(colour="white", shape=21, size = 4, 
     aes(fill = factor(label))) + 
     scale_fill_manual(values=c("blue", "cyan4"))

b $ b

如果你还需要 color 的不同颜色，那么：

ggplot(df, aes(own, method)) + 
      geom_point(aes(colour=factor(label), 
      fill = factor(label)), shape=21, size = 4) + 
      scale_fill_manual(values=c("blue", "cyan4")) + 
      scale_colour_manual(values=c("white", "black"))
