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.have_units() Function

The Axis.have_units() function in axis module of matplotlib library is used to check whether the units are set on any axis.

Syntax: Axis.have_units(self)

Parameters: This method does not accepts any parameter.

Return value: This method return True if units are set on any axis.

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

Example 1:

Python3

# Implementation of matplotlib function 
from matplotlib.axis import Axis 
import matplotlib.pyplot as plt  
     
fig, axs = plt.subplots()  
axs.plot([1, 2, 3])  
    
axs.set_title("Units are set on any axis : "
              +str(axs.xaxis.have_units()))    
  
fig.suptitle('matplotlib.axis.Axis.have_units() \ 
function Example\n', fontweight ="bold")   
    
plt.show()  

Output:

Example 2:

Python3

# Implementation of matplotlib function 
from matplotlib.axis import Axis 
import matplotlib.pyplot as plt  
      
fig, ax1 = plt.subplots( )  
ax1.set_xscale("log")  
ax1.set_yscale("log")  
ax1.set_adjustable("datalim")  
    
ax1.plot([1, 3, 34, 4, 46, 3, 7, 45, 10],  
         [1, 9, 27, 8, 29, 84, 78, 19, 48],  
          "o-", color ="green")  
    
ax1.set_xlim(1e-1, 1e2)  
ax1.set_ylim(1, 1e2)  
    
w = Axis.have_units(ax1.yaxis)  
    
print("Value Return by have_units() :", w)    
  
fig.suptitle('matplotlib.axis.Axis.have_units() \ 
function Example\n', fontweight ="bold")   
    
plt.show()
