ggplot中geom_point(scale_colour_manual)中的填充和边框颜色 [英] Fill and border colour in geom_point (scale_colour_manual) in ggplot

问题描述

我正在使用 ggplot 绘制散点图.我想要具有特定颜色和填充的点(例如在 plot、colour="blue"、fill="cyan4" 中)，但我不能不知道怎么做.到目前为止，我所拥有的是:

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) +  

(在之前的 geom_point 中，我尝试添加 shape=21，就像我在 plot 中所做的那样)

(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.

这是我在没有shape=21"的情况下得到的

This is what i get without "shape=21"

这就是我添加shape=21"时得到的结果.在这两种情况下，它都会忽略 scale_fill

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

我还尝试在 geom_point 中添加 fill=c("blue","re​​d")，但 R 抱怨:错误:设置美学的长度不兼容: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".

有什么关于如何获得它的建议吗?我的代码中的 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！

数据 (df) 看起来像:

Data (df) looks like:

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 到 25 的形状.这些是具有 colour 和 fill 属性的那些:

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"))

如果您还希望 colour 有不同的颜色，那么:

If you want different colours for colour as well, then:

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"))
