matplotlib Integration with TeX/LaTeX Saving and exporting plots that use TeX
Example
In order to include plots created with matplotlib in TeX documents, they should be saved as pdf or eps files. In this way, any text in the plot (including TeX formulae) is rendered as text in the final document.
import matplotlib.pyplot as plt
plt.rc(usetex=True)
x = range(0, 10)
y = [t**2 for t in x]
z = [t**2+1 for t in x]
plt.plot(x, y, label=r'$\beta=\alpha^2$')
plt.plot(x, z, label=r'$\beta=\alpha^2+1$')
plt.xlabel(r'$\alpha$')
plt.ylabel(r'$\beta$')
plt.legend(loc=0)
plt.savefig('my_pdf_plot.pdf') # Saving plot to pdf file
plt.savefig('my_eps_plot.eps') # Saving plot to eps file
Plots in matplotlib can be exported to TeX code using the pgf macro package to display graphics.
import matplotlib.pyplot as plt
plt.rc(usetex=True)
x = range(0, 10)
y = [t**2 for t in x]
z = [t**2+1 for t in x]
plt.plot(x, y, label=r'$\beta=\alpha^2$')
plt.plot(x, z, label=r'$\beta=\alpha^2+1$')
plt.xlabel(r'$\alpha$')
plt.ylabel(r'$\beta$')
plt.legend(loc=0)
plt.savefig('my_pgf_plot.pgf')
Use the rccommand to change the TeX engine used
plt.rc('pgf', texsystem='pdflatex') # or luatex, xelatex...
To include the .pgf figure, write in your LaTeX document
\usepackage{pgf}
\input{my_pgf_plot.pgf}
