在 Gadfly (Julia) 箱线图中指定颜色

Question

我正在尝试使用 Gadfly 重现 this Seaborn 图。

我目前的代码是：

using CSV, DataFrames, Gadfly

download("https://raw.githubusercontent.com/mwaskom/seaborn-data/master/tips.csv", "tips.csv")
tips = DataFrame(CSV.File("tips.csv"));

plot(
    tips, 
    x = :day, 
    y = :total_bill, 
    color = :smoker, 
    Geom.boxplot, 
    Scale.x_discrete(levels = ["Thur", "Fri", "Sat", "Sun"]), 
    Theme(
        key_position = :top, 
        boxplot_spacing = 20px
        ), 
    )

我想指定颜色“绿色”和“紫色”以匹配 Seaborn 图。有什么关于如何在 Gadfly 中执行此操作的建议吗？

其他：

如何设置smoker顺序从yes到no？

Answer 1

您需要添加一行 Scale.color_discrete_manual:

using CSV, DataFrames, Gadfly

download(
    "https://raw.githubusercontent.com/mwaskom/seaborn-data/master/tips.csv",
    "tips.csv",
)
tips = DataFrame(CSV.File("tips.csv"));

plot(
    tips,
    x = :day,
    y = :total_bill,
    color = :smoker,
    Geom.boxplot,
    Scale.x_discrete(levels = ["Thur", "Fri", "Sat", "Sun"]),
    Scale.color_discrete_manual("purple", "green", order=[2, 1]),
    Theme(key_position = :top, boxplot_spacing = 20px),
)
