Matplotlib.axis.Axis.update() function in Python

Matplotlib is a library in Python and it is numerical – mathematical extension for NumPy library. It is an amazing visualization library in Python for 2D plots of arrays and used for working with the broader SciPy stack.

Matplotlib.axis.Axis.update() Function

The Axis.update() function in axis module of matplotlib library is used to update this artist’s properties from the dictionary props. 

Syntax: Axis.update(self, props) 

Parameters: This method accepts the following parameters. 

• props: This parameter is the dictionary of the properties.

Return value: This method does not return any value. 

Below examples illustrate the matplotlib.axis.Axis.update() function in matplotlib.axis:

Example 1:

Python3

# Implementation of matplotlib function
from matplotlib.axis import Axis
import matplotlib.pyplot as plt
import numpy as np


np.random.seed(10**7)
geeks = np.random.randn(100)

fig, ax = plt.subplots()
ax.acorr(geeks, usevlines = True,
         normed = True,
         maxlags = 80, lw = 3)

ax.grid(True)

prop = {'xticks': np.array([-10., -5.,
                            0., 5., 10.]),
        'yticks': np.array([-0.2,  0.2,
                            0.6, 1., 1.4]),
        'ylabel': None, 'xlabel': None}

Axis.update(ax, prop)

plt.title('matplotlib.axis.Axis.update() \
function Example', fontweight ="bold")

plt.show()

Output:

Example 2:

Python3

# Implementation of matplotlib function
from matplotlib.axis import Axis
import numpy as np
import matplotlib.pyplot as plt


xx = np.random.rand(16, 30)

fig, ax = plt.subplots()

m = ax.pcolor(xx)
m.set_zorder(-20)
prop = {'autoscalex_on': False}

Axis.update(ax, prop)

plt.title('matplotlib.axis.Axis.update() \
function Example', fontweight ="bold")

plt.show()
