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
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
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))
