如何在geom_bar中更改AE的颜色填充

我有以下代码：

  ggplot(aes(x = Education)) + 
  geom_bar(aes(fill = P_3_1, P_3_2)) +
  facet_wrap(~Education) +
  labs(y = 'Qunatity', title = 'Answers for group "P_3" 
       based on education') +
  theme_bw()

我想以下面的方式获得GEOM_BAR，并具有两种颜色。是可能的还是代码的这一部分：fill = p_3_1，p_3_2 需要更改吗？我只有一个彩色的灰色条。

原文

I have below code:

  ggplot(aes(x = Education)) + 
  geom_bar(aes(fill = P_3_1, P_3_2)) +
  facet_wrap(~Education) +
  labs(y = 'Qunatity', title = 'Answers for group "P_3" 
       based on education') +
  theme_bw()

I want to get geom_bar as below with two colours.
Is that possible or this part of code: fill = P_3_1, P_3_2
needs to be changed?
I'm getting just one coloured gray bars.

如果您可以提供这样的小示例，那就更好了。您的填充可能是下面的单列？

library(tidyverse)

tribble(
  ~Education, ~quantity, ~fill,
  "a", 1000, "P_3_1",
  "a", 2000, "P_3_2",
  "b", 3000, "P_3_1", 
  "b", 4000, "P_3_2"
) |> 
  ggplot(aes(Education, quantity, fill = fill)) + 
  geom_col() +
  labs(y = 'Qunatity', title = 'Answers for group "P_3" based on education') +
  theme_bw()

It's better if you can provide a small reproducible example like this. Your fill probably needs to be a single column per below?

library(tidyverse)

tribble(
  ~Education, ~quantity, ~fill,
  "a", 1000, "P_3_1",
  "a", 2000, "P_3_2",
  "b", 3000, "P_3_1", 
  "b", 4000, "P_3_2"
) |> 
  ggplot(aes(Education, quantity, fill = fill)) + 
  geom_col() +
  labs(y = 'Qunatity', title = 'Answers for group "P_3" based on education') +
  theme_bw()
