Text and mathtext using pyplot#

Set the special text objects title, xlabel, and ylabel through the dedicated pyplot functions. Additional text objects can be placed in the axes using text.

You can use TeX-like mathematical typesetting in all texts; see also Writing mathematical expressions.

import matplotlib.pyplot as plt
import numpy as np

t = np.arange(0.0, 2.0, 0.01)
s = np.sin(2*np.pi*t)

plt.plot(t, s)
plt.text(0, -1, r'Hello, world!', fontsize=15)
plt.title(r'$\mathcal{A}\sin(\omega t)$', fontsize=20)
plt.xlabel('Time [s]')
plt.ylabel('Voltage [mV]')
plt.show()
$\mathcal{A}\sin(\omega t)$
