Matplotlib.pyplot.ylabel() in Python

Matplotlib is a very powerful plotting library useful for those working with Python and NumPy. And for making statistical interference, it becomes very necessary to visualize our data and Matplotlib is the tool that can be very helpful for this purpose.

matplotlib.pyplot.ylabel()

This function sets the label for the y-axis of the plot.

Syntax: matplotlib.pyplot.ylabel(ylabel, fontdict=None, labelpad=None) Parameters: ylabel: The name of the label fontdict: Adds the font styles to the label labelpad: This helps us to set the spacing between label and the axis

Example #1: Python3 1==

import matplotlib.pyplot as plt

# setting x values
x =['Geeks', 'for', 'geeks', 'tutorials']

# Setting y values 
y =[1, 2, 3, 4]

# Adding label on the y-axis
plt.ylabel('Numbers label')

# plotting the graph
plt.plot(x, y)

Output: Example #2: Python3 1==

import matplotlib.pyplot as plt

x =['Geeks', 'for', 'geeks', 'tutorials']
y =[1, 2, 3, 4]

# Adding space between label and
# axis by setting labelpad
plt.ylabel('Numbers label', labelpad = 50)

plt.plot(x, y)

Output: Example #3: Python3 1==

import matplotlib.pyplot as plt

x =['Geeks', 'for', 'geeks', 'tutorials']
y =[1, 2, 3, 4]

# Setting font dictionary 
font = {'family': 'Verdana',
        'color':  'green',
        'size': 20,
        }

# Adding the font styles to the label
plt.ylabel('Numbers label', fontdict = font)

plt.plot(x, y)

Output:
