How to plot an array in Python using Matplotlib?

To plot an array in Python, we can take the following steps −

  • Set the figure size and adjust the padding between and around the subplots.
  • Create two arrays, x and y, using numpy.
  • Set the title of the curve using title() method.
  • Plot x and y data points, with red color.
  • To display the figure, use show() method.


import numpy as np
import matplotlib.pyplot as plt

plt.rcParams["figure.figsize"] = [7.50, 3.50]
plt.rcParams["figure.autolayout"] = True

x = np.array([5, 4, 1, 4, 5])
y = np.sort(x)

plt.title("Line graph")
plt.plot(x, y, color="red")
