Plotly.js renders LaTeX in titles, axis labels, annotations, and legend entries when MathJax is loaded on the page. Wrap the expression in $ delimiters, as in the example below.

Plotly.js v4 supports MathJax v3 and v4, and uses the tex-svg component. Load one of the following before plotly.js:

<!-- MathJax v3 -->
<script src="https://cdn.jsdelivr.net/npm/[email protected]/es5/tex-svg.js"></script>
<!-- or MathJax v4 -->
<script src="https://cdn.jsdelivr.net/npm/mathjax@4/tex-svg.js"></script>

MathJax v2 is no longer supported. If your page loads MathJax.js?config=TeX-MML-AM_CHTML, replace it with one of the tags above — the ?config= query string is not used from MathJax v3 onward, since the component is selected by the file you load.

// remember to load MathJax v3 or v4 (tex-svg.js) - see https://plotly.com/javascript/LaTeX/
