在R中为Boxplot添加颜色

Question

ClientScript.RegisterClientScriptBlock

我有此代码，所有方框均为绿色，我可以添加些什么以使方框具有不同的颜色

Answer 1

您只需要为颜色添加一个因数（x_axis_var）。

boxplot(mtcars$mpg ~ mtcars$cyl, 
        main = "Box Plot of Mileage vs Number of Cylinders", 
        xlab = "Number of Cylinders", 
        ylab = "Miles per Gallon", col = factor(mtcars$cyl))

或提供颜色矢量：

boxplot(mtcars$mpg ~ mtcars$cyl, 
        main = "Box Plot of Mileage vs Number of Cylinders", 
        xlab = "Number of Cylinders", 
        ylab = "Miles per Gallon", col = c("blue","red","green"))
