I am trying to reproduce [this](https://seaborn.pydata.org/examples/grouped_boxplot.html) Seaborn plot using Gadfly.

The code I have so far is:

```
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
        ), 
    )

```

I would like to specify the colors “green” and “purple” to match the Seaborn plot.  
Any suggestions how to do this in Gadfly?

Additional:

- Is there a better way to order the days (from `thur` to `sun`)
- How to set the `smoker` order from `yes` to `no`?

`Scale.color_discrete_manual("green", "purple", order = [2, 1])` should work fine.

```julia
set_default_plot_size(18cm, 12cm)

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

```
