Axes.flat means a 1D iterator over the array. Let's take an example to see how to use axes.flat.
Steps
Set the figure size and adjust the padding between and around the subplots.
Create a figure and a set of subplots using subplots() method.
Create x and y data points using numpy.
Use axes.flat and iterate all the axes (step 2).
Plot x and y data points using plot() method.
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 fig, axes = plt.subplots(nrows=2, ncols=3) x = np.random.rand(10) y = np.random.rand(10) for _, ax in enumerate(axes.flat): ax.plot(x, y) plt.show()
