Matplotlib.axis.Axis.get_gridlines() 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.get_gridlines() Function

The Axis.get_gridlines() function in axis module of matplotlib library is used to get the grid lines as a list of Line2D instance.

Syntax: Axis.get_gridlines(self) 

Parameters: This method does not accepts any parameters. 

Return value: This method returns the grid lines as a list of Line2D instance. 

Below examples illustrate the matplotlib.axis.Axis.get_gridlines() function in matplotlib.axis:
Example 1:

Python3

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

fig, ax2 = plt.subplots()
x = []

for i in range(1,11):
    j = random.randint(1,10)
    x.append(i*j)
ax2.plot(x)

print("Value of get_gridlines() :")
for i in ax2.xaxis.get_gridlines():
    print(i)

fig.suptitle("Matplotlib.axis.Axis.get_gridlines()\
Function Example", fontsize = 12, fontweight ='bold')

plt.show()

Output:

Value of get_gridlines() :
Line2D((0,0),(0,1))
Line2D((0,0),(0,1))
Line2D((0,0),(0,1))
Line2D((0,0),(0,1))
Line2D((0,0),(0,1))
Line2D((0,0),(0,1))
Line2D((0,0),(0,1))

Example 2:

Python3

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

fig, ax = plt.subplots()

ax.plot([5,1], label="Label 1")
ax.plot([3,0], label="Label 2")

legend = ax.legend(loc="upper right")
offset = matplotlib.text.OffsetFrom(legend, (1.0, 0.0))

ax.annotate("String - Info",
            xy = (0,0),
            size = 14,
            xycoords = 'figure fraction',
            xytext = (0,-20),
            textcoords = offset,
            horizontalalignment = 'right',
            verticalalignment = 'top')

fig.canvas.draw()
ax.grid()

print("Value of get_gridlines() :")
for i in ax.yaxis.get_gridlines():
    print(i)

fig.suptitle("Matplotlib.axis.Axis.get_gridlines()\
Function Example", fontsize = 12, fontweight ='bold')

plt.show()

Output:

Value of get_gridlines() :
Line2D((0,0),(1,0))
Line2D((0,0),(1,0))
Line2D((0,0),(1,0))
Line2D((0,0),(1,0))
Line2D((0,0),(1,0))
Line2D((0,0),(1,0))
Line2D((0,0),(1,0))
Line2D((0,0),(1,0))
