Solution is using text mode for the symbol (\mbox{\DJ} inside math or \text{\DJ} if package amstext or amsmath is loaded):... plt.xlabel(r'$\mu$') plt.title(r'\DJ') plt.savefig('test.pdf') Common Symbols. You can use a subset TeXmarkup in any Matplotlib text string by placing it inside a pair of dollar signs ($). can be used. import matplotlib.pyplot as plt plt.rc(usetex = True) or accessing the rcParams: import matplotlib.pyplot as plt params = {'tex.usetex': True} plt.rcParams.update(params) TeX uses the backslash \ for commands and symbols, which can conflict with special characters in Python strings. I have recently drawn up a lot of plots in Python (matplotlib), but then I realized that I couldn't find their LaTeX equivalents.I am specifically looking to generate circle, square, and diamond symbols which are half-filled (left, right, top or bottom). Below we give a partial list of commonly used mathematical symbols. For example, the title() function that draws a chart title. The LaTeX option is activated by setting text.usetex: True in your rc settings. # math text plt.title(r'$\alpha > \beta$') To make subscripts and superscripts, use the '_' and '^' symbols … Nice job! We can also render Greek alphabets and many more symbols in Matplotlib using the Tex format. import matplotlib.pyplot as plt import numpy as np %matplotlib inline x = np.linspace(0,3) y = np.sin(x) plt.plot(x,y) plt.title(r'$\beta \rho \lambda \xi$',fontsize=30) As far as I recall, it's$\times$but that's not working in a matplotlib plot title (perhaps because matplotlib doesn't implement that particular symbol?). along with the appropriate declarations for text.latex.preamble to be able to use \boldsymbol, it would be nice to be able to keep. With matplotlib You can enter the LaTeX expression directly as an argument of various functions that can accept it. Any Idea why this could be? text.usetex = False with something like. When executing the following code in python using jupyter/ipython, the Latex symbols are not displayed correctly. with the "stix" options it works fine; however the most nice LaTeX result is by changing matplotlib.rcParams['mathtext.fontset'] = 'stix' into matplotlib.rcParams['mathtext.fontset'] = 'cm'.This is "computer modern" the font of LaTeX.Eventually changing the family into matplotlib.rcParams['font.family'] = 'cmu serif' may work, but in my case I had problem with the minus … title(r'$\boldsymbol\psi_N$=0.95') to achieve bold symbols. See the LaTeX WikiBook (Mathematics) and the Detexify App to find any symbol you can think of! Text handling with matplotlib's LaTeX support is slower than matplotlib's very capable mathtext, but is more flexible, since different LaTeX packages (font packages, math packages, etc.) See the LaTeX WikiBook for more information (especially the section on mathematics). Most other symbols can be inferred from these examples. import matplotlib.pyplot as plt plt.rc(usetex = True) or accessing the rcParams: import matplotlib.pyplot as plt params = {'tex.usetex': True} plt.rcParams.update(params) TeX uses the backslash \ for commands and symbols, which can conflict with special characters in Python strings. import matplotlib.pyplot as plt %matplotlib inline plt.title(r'$\alpha > \beta$') With IPython Notebook in a Markdown Cell You can enter the LaTeX expression between two import matplotlib matplotlib.rcParams['text.usetex'] = True We also need to have LaTex, dvipng and Ghostscript(Version 9.0 or later) to render the LaTex formulae and add all the installations dependencies to the PATH. I get something like "A imes B" (with imes in latex font) for the title "A$\times$B". import matplotlib.pyplot as plt plt.rc(usetex = True) or accessing the rcParams: import matplotlib.pyplot as plt params = {'tex.usetex': True} plt.rcParams.update(params) TeX uses the backslash \ for commands and symbols, which can conflict with special characters in Python strings.
