Table of Contents
To add a title to a pandas dataframe, you can use the .title() method. This method will add the title at the top of the dataframe. The title should be a string that can be used to give the dataframe a name. Additionally, you can also use the .rename() method to change the column names of the dataframe to give them meaningful names. This will make the dataframe easier to understand and interpret.
You can use the set_title() function from matplotlib to add a title to a table created from a pandas DataFrame:
ax.set_title('Some Title')
The following example shows how to use this function in practice.
Example: Add Table Title to Pandas DataFrame
Suppose we have the following pandas DataFrame that shows the points and assists for various basketball teams:
import pandas as pd #create DataFrame df = pd.DataFrame({'team': ['A', 'B', 'C', 'D', 'E', 'F', 'G', 'H'], 'points': [18, 22, 19, 14, 14, 11, 20, 28], 'assists': [5, 7, 7, 9, 12, 9, 9, 4]}) #view DataFrame print(df) team points assists 0 A 18 5 1 B 22 7 2 C 19 7 3 D 14 9 4 E 14 12 5 F 11 9 6 G 20 9 7 H 28 4
We can use the following code to create a table in matplotlib that displays the values from the DataFrame and use set_title() to specify a title for the table:
import matplotlib.pyplot as plt
#initialize figure
fig = plt.figure(figsize = (8, .2))
ax = fig.add_subplot(111)
#create table
ax.table(cellText = df.values, rowLabels = df.index,
colLabels = df.columns, cellLoc='center')
#add title to table
ax.set_title('Points and Assists by Team')
#turn axes off
ax.axis('off')
Note: You can find the complete documentation for the table() function in matplotlib .
Notice that the title ‘Points and Assists by Team’ has been added above the table.
Also note that you can use the fontdict and loc arguments to modify the title font and title location:
import matplotlib.pyplot as plt
#initialize figure
fig = plt.figure(figsize = (8, .2))
ax = fig.add_subplot(111)
#create table
ax.table(cellText = df.values, rowLabels = df.index,
colLabels = df.columns, cellLoc='center')
#add title to table
ax.set_title('Points and Assists by Team',
fontdict={'fontsize': 20,
'fontweight': 'bold',
'color': 'steelblue'},
loc='left')
#turn axes off
ax.axis('off')
Notice that the title font is now larger, bold, left-aligned, and blue.
Refer to the for a complete list of ways you can modify the appearance of the title.
