Chapter 9: Matplotlib

Bonus task

We will end this lesson with a bonus Matplotlib task from Josiah!

Task 9: Grand challenge!

You are given a piece of code to plot two lines on the same graph.

import numpy as np
import matplotlib.pyplot as plt

resolution = 1000
x = np.linspace(0, 50, resolution)
y = np.sin(x)
z = np.exp(y)

plt.figure(1)
plt.plot(x, y, "b")
plt.plot(x, z, "r")

plt.show()

Now, try plotting each graph in a different subplot instead, side-by-side on a single Figure.

Multiple subplots in the same figure

Hint: Check out plt.subplots() or plt.subplot().

import numpy as np
import matplotlib.pyplot as plt

resolution = 1000
x = np.linspace(0, 50, resolution)
y = np.sin(x)
z = np.exp(y)

fig, (axis1, axis2) = plt.subplots(1, 2)
axis1.plot(x, y, "b")
axis2.plot(x, z, "r")

plt.show()
