Adding a line to a scatter plot using Python's Matplotlib

To add a line to a scatter plot using Python's Matplotlib, we can take the following steps −

  • Set the figure size and adjust the padding between and around the subplots.
  • Initialize a variable, n, for number of data points.
  • Plot x and y data points using scatter() method.
  • Plot a line using plot() method.
  • Limt the X-axis using xlim() method.
  • To display the figure, use show() method.


import numpy as np
from matplotlib import pyplot as plt

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

n = 100
x = np.random.rand(n)
y = np.random.rand(n)

plt.scatter(x, y, c=x)
plt.plot([0.1, 0.4, 0.3, 0.2])
plt.xlim(0, 1)
