Question

我想以不同方式为我的boxplot变量着色。我看了here并尝试了下面的内容，但是绘图框都是标准的白色（我在Type中有6个因子）。我应该改变什么？

library(ggplot2)
ggplot(PGcounts, aes(Type, Word)) + 
            geom_boxplot() + 
            coord_trans(y = "log10") +
            scale_fill_manual(values = c("white","white","white","red","blue","white"))

Answer 1

您也可以在原始代码中从geom_boxplot()更改为geom_boxplot(aes(fill=Type))。

例如：

ggplot(PGcounts, aes(Type, Word)) + 
        geom_boxplot(aes(fill=Type)) + 
        coord_trans(y = "log10") +
        scale_fill_manual(values = c("white","white","white","red","blue","white"))

Answer 2

需要改变的是

geom_boxplot() +

到

geom_boxplot(fill = c("white","white","white","red","blue","white")) +

并删除

scale_fill_manual(values = c("white","white","white","red","blue","white"))
