如何为 seaborn 箱线图添加标题

Question

Seems pretty Googleable but haven't been able to find something online that works.

I've tried both sns.boxplot('Day', 'Count', data= gg).title('lalala') and sns.boxplot('Day', 'Count', data= gg).suptitle('lalala') . None worked. I think it might be because I'm also working with matplotlib.

Answer 1

Seaborn box plot returns a matplotlib axes instance. Unlike pyplot itself, which has a method plt.title() , the corresponding argument for an axes is ax.set_title() . Therefore you need to call

sns.boxplot('Day', 'Count', data= gg).set_title('lalala')

A complete example would be:

import seaborn as sns
import matplotlib.pyplot as plt

tips = sns.load_dataset("tips")
sns.boxplot(x=tips["total_bill"]).set_title("LaLaLa")

plt.show()

Of course you could also use the returned axes instance to make it more readable:

ax = sns.boxplot('Day', 'Count', data= gg)
ax.set_title('lalala')
ax.set_ylabel('lololo')

Answer 2

sns.boxplot() function returns Axes(matplotlib.axes.Axes) object. please refer the documentation you can add title using 'set' method as below:

sns.boxplot('Day', 'Count', data=gg).set(title='lalala')

you can also add other parameters like xlabel, ylabel to the set method.

sns.boxplot('Day', 'Count', data=gg).set(title='lalala', xlabel='its x_label', ylabel='its y_label')

There are some other methods as mentioned in the matplotlib.axes.Axes documentaion to add tile, legend and labels.

Answer 3

Try adding this at the end of your code:

import matplotlib.pyplot as plt

plt.title('add title here')

Answer 4

For a single boxplot:

import seaborn as sb
sb.boxplot(data=Array).set_title('Title')

For more boxplot in the same plot:

import seaborn as sb
sb.boxplot(data=ArrayofArray).set_title('Title')

eg

import seaborn as sb
myarray=[78.195229, 59.104538, 19.884109, 25.941648, 72.234825, 82.313911]
sb.boxplot(data=myarray).set_title('myTitle')

Answer 5

.set_title('') can be used to add title to Seaborn Plot

import seaborn as sb
sb.boxplot().set_title('Title')

Answer 6

try this

import seaborn as sns
g = sns.catplot(x='Day', y='Count', data=gg)
g.set_title('LaLa')
