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()
