Python : Matplotlib annotate line break (with and without latex)

Question

I have a very basic question : how to do a line break with matplotlib in python with an \"annotate\" command. I tried \"\\\" and \"\\n\" but it does not work. And how to do

Answer 1

What exactly did you try?

Were you, by chance, using a raw string (e.g. r"whatever")?

'\n' works perfectly, but if you're using a raw string to avoid latex sequences being interpreted as an escape, it will be interpreted by python as '\' and 'n' instead of a newline.

As an example:

import matplotlib.pyplot as plt

plt.annotate('Testing\nThis\nOut', xy=(0.5, 0.5))

plt.show()

On the other hand, if we use a raw string:

import matplotlib.pyplot as plt

plt.annotate(r'Testing\nThis\nOut', xy=(0.5, 0.5))

plt.show()
