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() |
