To draw a line graph in Matplotlib, use the plot() method. By default, plot() creates a line. The points used are the x and y coordinates of a line. Before moving further, we’ve prepared a video tutorial to plot a line graph in Matplotlib:

Example

Let us see an example wherein we will plot the x and y points:

import matplotlib.pyplot as plt
import numpy as np

# Data to plot a line
xPts = np.array([1, 9])
yPts = np.array([4, 12])

# Plot a line graph using the pyplot.plot() method
# The two parameters are x and y axis
plt.plot(xPts, yPts)

# Display the figure
plt.show()

Output
