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. There are various plots which can be used in Pyplot are Line Plot, Contour, Histogram, Scatter, 3D Plot, etc.
matplotlib.pyplot.get_fignums() method
The get_fignums() method in pyplot module of matplotlib library is used to get the list of existing figure numbers.
Syntax: matplotlib.pyplot.get_fignums()
Parameters: This method does not accept any parameters.
Returns: This method returns the list of existing figure numbers.
Below examples illustrate the matplotlib.pyplot.get_fignums() function in matplotlib.pyplot:
Example 1:
import numpy as np
import matplotlib.pyplot as plt
x = np.linspace( 0 , 10 , 500 )
y = np.sin(x * * 2 ) + np.cos(x)
plt.plot(x, y, label = 'Line 1' )
plt.plot(x, y - 0.6 , label = 'Line 2' )
w = plt.get_fignums()
plt.text( 2 , 1.98 ,
"List of existing figure numbers : "
+ str (w),
fontsize = 12 )
plt.title('matplotlib.pyplot.get_fignums() function\
Example', fontweight = "bold" )
plt.show()
|
Output:
Example 2:
import matplotlib.pyplot as plt
import numpy as np
t = np.arange( 0.01 , 5.0 , 0.01 )
s = np.exp( - t)
plt.plot(t, s)
plt.ylim( 1 , 0 )
plt.ylabel( 'Display Y-axis Label' , fontweight = 'bold' )
plt.grid( True )
w = plt.get_fignums()
plt.text( 0.9 , 0.58 ,
"List of existing figure numbers : "
+ str (w),
fontsize = 12 )
plt.title('matplotlib.pyplot.get_fignums() function\
Example', fontweight = "bold" )
plt.show()
