Matplotlib is a library in Python and it is numerical – mathematical extension for NumPy library. The Axes Class contains most of the figure elements: Axis, Tick, Line2D, Text, Polygon, etc., and sets the coordinate system. And the instances of Axes supports callbacks through a callbacks attribute.
matplotlib.axes.Axes.set_axisbelow() Function
The Axes.set_axisbelow() function in axes module of matplotlib library is used to set whether axis ticks and gridlines are above or below most artists.
Syntax: Axes.set_axisbelow(self, b)
Parameters: This method accept only one parameters.
b: This parameter contains a boolean value and it’s possible values are : True, False or “line”.
Returns:This method does not returns anything.
Below examples illustrate the matplotlib.axes.Axes.set_axisbelow() function in matplotlib.axes:
Example 1:
import matplotlib.pyplot as plt
import numpy as np
np.random.seed( 19680801 )
all_data = [np.random.normal( 0 , std, size = 100 ) for std in range ( 1 , 6 )]
labels = [ 'x1' , 'x2' , 'x3' , 'x4' , 'x5' ]
fig, ax = plt.subplots()
bplot = ax.boxplot(all_data,
vert = True ,
patch_artist = True ,
labels = labels)
colors = [ 'lightpink' , 'lightblue' , 'lightgreen' ,
"lightgrey" , "yellow" ]
for patch, color in zip (bplot[ 'boxes' ], colors):
patch.set_facecolor(color)
ax.yaxis.grid( True , color = "green" , lw = 2 )
ax.set_axisbelow( True )
ax.set_xlabel( 'Samples' )
ax.set_ylabel( 'Observed values' )
ax.set_title('matplotlib.axes.Axes.set_axisbelow() \
Example\n ', fontsize = 12, fontweight =' bold')
plt.show()

Output:
Example 2:
