How to add a title to Seaborn Facet Plot
PythonVisualizationSeabornPython Problem Overview
How do I add a title to this Seaborne plot? Let's give it a title 'I AM A TITLE'.
tips = sns.load_dataset("tips")
g = sns.FacetGrid(tips, col="sex", row="smoker", margin_titles=True)
g.map(sns.plt.scatter, "total_bill", "tip")
Python Solutions
Solution 1 - Python
Updating slightly, with seaborn 0.11.1:
Seaborn's relplot function creates a FacetGrid and gives each subplot its own explanatory title. You can add a title over the whole thing:
import seaborn as sns
tips = sns.load_dataset('tips')
rp = sns.relplot(data=tips, x='total_bill', y='tip',
col='sex', row='smoker',
kind='scatter')
# rp is a FacetGrid;
# relplot is a nice organized way to use it
rp.fig.subplots_adjust(top=0.9) # adjust the Figure in rp
rp.fig.suptitle('ONE TITLE FOR ALL')
If you create the FacetGrid directly, as in the original example, it automatically adds column and row labels instead of individual subplot titles. We can still add a title to the whole thing:
from matplotlib.pyplot import scatter as plt_scatter
g = sns.FacetGrid(tips, col='sex', row='smoker',
margin_titles=True)
g.map(plt_scatter, 'total_bill', 'tip')
g.fig.subplots_adjust(top=0.9)
g.fig.suptitle('TITLE!')
The FacetGrid objects are built with matplotlib Figure objects, so we can use subplots_adjust, suptitle that may be familiar from matplotlib in general.
Solution 2 - Python
g.fig.subplots_adjust(top=0.9)
g.fig.suptitle('Title', fontsize=16)

Solution 3 - Python
In ipython notebook, this worked for me!
sns.plt.title('YOUR TITLE HERE')
Solution 4 - Python
What worked for me was:
sns.plt.suptitle('YOUR TITLE HERE')
Solution 5 - Python
The answers using sns.plt.title() and sns.plt.suptitle() don't work anymore.
Instead, you need to use matplotlib's title() function:
import matplotlib.pyplot as plt
sns.FacetGrid(<whatever>)
plt.title("A title")
Solution 6 - Python
plt.suptitle("Title")
or
plt.title("Title")
This worked for me.
Solution 7 - Python
The title will not be center aligned with the subplot titles.
To set the position of the title you can use
plt.suptitle("Title", x=center)
In my case, my subplots were in a 2x1 grid, so I was able to use
bbox = g.axes[0,0].get_position() to find the bounding box and then center=0.5*(bbox.x1+bbox.x2)
