Introduction
Matplotlib is a library in Python used for data visualization. It supports accented characters via TeX mathtext or Unicode. This tutorial will demonstrate how to use accented text in Matplotlib.
VM Tips
After the VM startup is done, click the top left corner to switch to the Notebook tab to access Jupyter Notebook for practice.
Sometimes, you may need to wait a few seconds for Jupyter Notebook to finish loading. The validation of operations cannot be automated because of limitations in Jupyter Notebook.
If you face issues during learning, feel free to ask Labby. Provide feedback after the session, and we will promptly resolve the problem for you.
Using Mathtext
Mathtext is a feature in Matplotlib that allows you to use TeX commands to render mathematical symbols and equations. Mathtext also supports accented characters.
import matplotlib.pyplot as plt
## Mathtext demo
fig, ax = plt.subplots()
ax.plot(range(10))
ax.set_title(r'$\ddot{o}\acute{e}\grave{e}\hat{O}'
r'\breve{i}\bar{A}\tilde{n}\vec{q}$', fontsize=20)
## Shorthand is also supported and curly braces are optional
ax.set_xlabel(r"""$\"o\ddot o \'e\`e\~n\.x\^y$""", fontsize=20)
ax.text(4, 0.5, r"$F=m\ddot{x}$")
fig.tight_layout()
Using Unicode Characters
Matplotlib also supports the use of Unicode characters directly in strings.
import matplotlib.pyplot as plt
## Unicode demo
fig, ax = plt.subplots()
ax.set_title("GISCARD CHAHUTÉ À L'ASSEMBLÉE")
ax.set_xlabel("LE COUP DE DÉ DE DE GAULLE")
ax.set_ylabel('André was here!')
ax.text(0.2, 0.8, 'Institut für Festkörperphysik', rotation=45)
ax.text(0.4, 0.2, 'AVA (check kerning)')
plt.show()
Running the Code
To run the code, you must have Matplotlib installed. You can install Matplotlib using pip. Open the command prompt and type:
pip install matplotlib
