#35 Control order of boxplot

Boxplots often give more information if you order group in a specific order. This is feasible with seaborn. 

Here are 2 examples explaining the 2 main needs you can have:

Use a specific order

# library & dataset
import seaborn as sns
df = sns.load_dataset('iris')

# specific order
p1=sns.boxplot(x='species', y='sepal_length', data=df, order=["virginica", "versicolor", "setosa"])
#sns.plt.show()

By decreasing median

# library & dataset
import seaborn as sns
df = sns.load_dataset('iris')

# Find the order
my_order = df.groupby(by=["species"])["sepal_length"].median().iloc[::-1].index

# Give it to the boxplot
sns.boxplot(x='species', y='sepal_length', data=df, order=my_order)
#sns.plt.show()
