To have a function return a figure in Python (using Matplotlib), we can take the following steps −
Set the figure size and adjust the padding between and around the subplots.
Create x and y data points using numpy.
Make a function plot(x, y) that creates a new figure or activate an existing figure using figure() method.
Plot the x and y data points using plot() method; return fig instance.
Call plot(x, y) method and store the figure instance in a variable, f.
To display the figure, use show() method.
Example
import numpy as np from matplotlib import pyplot as plt plt.rcParams["figure.figsize"] = [7.50, 3.50] plt.rcParams["figure.autolayout"] = True def plot(x, y): fig = plt.figure() plt.plot(x, y) return fig x = np.linspace(-10, 10, 100) y = np.sin(x) f = plot(x, y) plt.show()
Output
