Matplotlib is a library in Python and it is numerical – mathematical extension for NumPy library. Pyplot is a state-based interface to a Matplotlib module which provides a MATLAB-like interface.
matplotlib.pyplot.delaxes() Function
The delaxes() function in pyplot module of matplotlib library is used to remove the Axes ax from its figure.
Syntax: matplotlib.pyplot.delaxes(ax=None)
Parameters: This method accept the following parameters that are described below:
- ax: This parameter is the axes which is to be removed. Its default value is None.
Below examples illustrate the matplotlib.pyplot.delaxes() function in matplotlib.pyplot:
Example #1:
import matplotlib.pyplot as plt
import numpy as np
fig, ax = plt.subplots()
ax.plot([ 1 , 2 , 3 ])
plt.delaxes()
plt.suptitle( 'matplotlib.pyplot.delaxes() function Example' ,
fontweight = "bold" )
plt.show()
|
Output:
Example #2:
import numpy as np
import matplotlib.pyplot as plt
dt = 0.01
t = np.arange( 0 , 30 , dt)
nse1 = np.random.randn( len (t))
r = np.exp( - t / 0.05 )
cnse1 = np.convolve(nse1, r, mode = 'same' ) * dt
s1 = np.cos(np.pi * t) + cnse1 + np.sin( 2 * np.pi * 10 * t)
fig, [ax1, ax2] = plt.subplots( 2 , 1 )
ax1.plot(t, s1)
ax1.set_xlim( 0 , 5 )
ax1.set_ylabel( 'value s1' )
ax1.grid( True )
ax2.psd(s1, 256 , 1. / dt)
ax2.set_ylabel( 'PSD(db)' )
ax2.set_xlabel( 'Frequency' )
plt.delaxes(ax = ax1)
plt.suptitle( 'matplotlib.pyplot.delaxes() function Example' ,
fontweight = "bold" )
plt.show()
