The default font is italics for mathematical symbols. This default can be changed using rcParams["mathtext.default"] (default: 'it'). For setting rcParams, see Customizing Matplotlib with style sheets and rcParams. For example, setting the default to regular allows you to use the same font for math text and regular non-math text.

May 10, 2017 · Writing mathematical expressions¶ You can use a subset TeX markup in any matplotlib text string by placing it inside a pair of dollar signs ($). Note that you do not need to have TeX installed, since matplotlib ships its own TeX expression parser, layout engine and fonts.

Mar 19, 2022 · I need to type Greek letters and the Angstrom symbol in labels of axes in a plot. So for example. fig.gca().set_xlabel("$wavelength\, (Angstrom)$") fig.gca().set_ylabel("$lambda$") except that I actually want "Angstrom" and "lambda" replaced by actual symbols. How should I do this? Thanks!

Mathematical expressions# Selected features of Matplotlib's math rendering engine.

matplotlib can render math text as, for instance, a plot title, because its target is the generated image. Like Kurt Kline said, you can display simple characters, but not complex expressions like a sum symbol or superscripts.

Learn how to use mathematical expressions in Matplotlib for effective data visualization. Explore the syntax and examples to enhance your plotting skills.

Jan 13, 2020 · matplotlib can display mathematical formulas, Greek letters, and mathematical symbols using a math rendering module known as mathtext. The mathtext module parses a subset of Donald Knuth’s TEX. mathematical typesetting language, and provides basic mathematical typesetting without any software other than matplotlib.
