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:
# Implementation of matplotlib function 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:
# Implementation of matplotlib function 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() |
Output:
