0 0 1 minute read

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_units() Function

The Axis.get_units() function in axis module of matplotlib library is used to get the units for axis.

Syntax: Axis.get_units(self)

Parameters: This method does not accepts any parameters.

Return value: This method return the units for axis.

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

Python3

# Implementation of matplotlib function 
from matplotlib.axis import Axis 
import random 
import matplotlib.lines as lines 
import matplotlib.patches as patches 
import matplotlib.text as text 
import matplotlib.collections as collections 
from basic_units import cm, inch 
import numpy as np 
import matplotlib.pyplot as plt 
   
fig, ax = plt.subplots() 
ax.xaxis.set_units(cm) 
ax.yaxis.set_units(cm) 
   
np.random.seed(19680801) 
   
line = lines.Line2D([2*cm, 8*cm], [0*cm, 2.5*cm], 
                    lw=2, color='green', axes=ax) 
ax.add_line(line) 
   
t = text.Text(3*cm, 2.5*cm,  
              'Line 1', 
              ha='left', 
              va='bottom', 
              axes=ax, 
              color='red') 
ax.add_artist(t) 
  
ax.grid(True) 
  
print("Value return by get_units() :", 
      ax.xaxis.get_units()) 
   
fig.suptitle("""matplotlib.axis.Axis.get_units() 
function Example\n""", fontweight ="bold")   
       
plt.show() 

Output:

Value return by get_units() : centimeters

Example 2:

Python3

# Implementation of matplotlib function 
from matplotlib.axis import Axis 
import numpy as np 
import matplotlib.pyplot as plt 
from basic_units import secs 
   
# create masked array 
data = (1, 2, 3, 4, 5, 6, 7, 8) 
mask = (1, 0, 1, 0, 0, 0, 1, 0) 
xsecs = secs * np.ma.MaskedArray(data, mask, float) 
   
fig, ax1 = plt.subplots() 
   
ax1.scatter(xsecs, xsecs) 
ax1.yaxis.set_units(secs) 
   
ax1.grid() 
  
print("Value return by get_units() :", 
      ax1.yaxis.get_units()) 
   
fig.suptitle("""matplotlib.axis.Axis.get_units() 
function Example\n""", fontweight ="bold")   
       
plt.show()
