"""
===============
Math fontfamily
===============
A simple example showcasing the new *math_fontfamily* parameter that can
be used to change the family of fonts for each individual text
element in a plot.
If no parameter is set, the global value
:rc:`mathtext.fontset` will be used.
"""
import matplotlib.pyplot as plt
fig, ax = plt.subplots(figsize=(6, 5))
# A simple plot for the background.
ax.plot(range(11), color="0.9")
# A text mixing normal text and math text.
msg = (r"Normal Text. $Text\ in\ math\ mode:\ "
r"\int_{0}^{\infty } x^2 dx$")
# Set the text in the plot.
ax.text(1, 7, msg, size=12, math_fontfamily='cm')
# Set another font for the next text.
ax.text(1, 3, msg, size=12, math_fontfamily='dejavuserif')
# *math_fontfamily* can be used in most places where there is text,
# like in the title:
ax.set_title(r"$Title\ in\ math\ mode:\ \int_{0}^{\infty } x^2 dx$",
math_fontfamily='stixsans', size=14)
# Note that the normal text is not changed by *math_fontfamily*.
