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:
# 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:
# 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() |
Output:
Value return by get_units() : seconds
