ggplot(data, aes(x=group, y=value, fill=group))+# Change filling colorgeom_boxplot() By running the previous R code, we have managed to create Figure 3, i.e. a boxplot with different filling colors for each box. Note that we could specify both the col and fill arguments at the ...
color="black") ch 输出: 相同的填充 在这里,我们将使用关键字填充。由于我们需要相同的颜色填充箱线图,我们将在 geom_boxplot( ) 中编写命令。默认情况下,异常值的填充为黑色。 例子: R实现 # Same fill color library(ggplot2) ch <- ggplot(chickwts,aes(x=feed,y=weight))+ geom_boxplot(fill="...
