Styling part of label in legend in matplotlib


Is it possible to have part of the text of a legend in a particular style, let's say, bold or italic?

As silvado mentions in his comment, you can use LaTeX rendering for more flexible control of the text rendering. See here for more information:

An example:

import numpy as np
import matplotlib.pyplot as plt
from matplotlib import rc

# activate latex text rendering
rc('text', usetex=True)

x = np.arange(10)
y = np.random.random(10)
z = np.random.random(10)

fig = plt.figure()
ax = fig.add_subplot(111)
ax.plot(x, y, label = r"This is \textbf{line 1}")
ax.plot(x, z, label = r"This is \textit{line 2}")

enter image description here

Note the 'r' before the strings of the labels. Because of this the \ will be treated as a latex command and not interpreted as python would do (so you can type \textbf instead of \\textbf).

Write between '$$'to force matplotlib to interpret it.

import matplotlib.pyplot as plt

plt.plot(range(10), range(10), label = "Normal text $\it{Italics}$")
