How to print out matplotlib in VS Code

Question

Just a small question. I have VS Code installed and trying it out with Python but no matter what I try I cannot get matplotlib plots to appear.

Here is a simple code that does NOT work

import mglearn
import matplotlib.pyplot as plt

X, y = mglearn.datasets.make_wave(n_samples=40) 
plt.plot(X, y, 'o') 
plt.ylim(-3, 3) 
plt.xlabel("Feature") 
plt.ylabel("Target")

No error with the code appears but also no plot. Thanks.

Please note mglearn comes from the following Github https://github.com/amueller/mglearn

Did you mean VS Code instead of Visio, in the title and tags? — ethguo

Looks like this has nothing to do with Microsoft Visio? I would also suggest you change the tags. — Nikolay

Try plt.show() at the end. And this additional line is just because the system asks me extra text for no reason.

Your code works. You need to ask for the picture to be shown plt.show() or to be saved plt.savefig().

Just add plt.show() and you will obtain:
