Draw a horizontal line line at specific position/annotate a Facetgrid in seaborn

Question

A have produced a boxplot with Facetgrid in seaborn the following way

# Import the dataset
tips = sns.load_dataset(\"tips\")

# Plot using Facegrid, separated by         


        

Answer 1

There is axhline and hlines. Simple example:

chart = sns.relplot(x="x", y="y", kind="line", data=df)

chart.axes[0][0].axhline(y = 10, color='black', linewidth=2, alpha=.7)
chart.axes[0][0].hlines( y = 20, color='black', linewidth=2, alpha=.7, 
                         xmin = 30, xmax = 50) 

Seems like hlines allows for min-max (documentation) but axhline doesn't.
