• Last Updated : 10 May, 2020

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.

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()`
