| # Math Configuration (v\<MERMAID_RELEASE_VERSION>+) | ||
|
|
||
| Mermaid supports rendering mathematical expressions through the [KaTeX](https://katex.org/) typesetter. | ||
|
|
||
| ## Usage | ||
|
|
||
| To render math within a diagram, surround the mathematical expression with the `$$` delimiter. | ||
|
|
||
| Note that at the moment, the only supported diagrams are below: | ||
|
|
||
| ### Flowcharts | ||
|
|
||
| ```mermaid-example | ||
| graph LR | ||
| A["$$x^2$$"] -->|"$$\sqrt{x+3}$$"| B("$$\frac{1}{2}$$") | ||
| A -->|"$$\overbrace{a+b+c}^{\text{note}}$$"| C("$$\pi r^2$$") | ||
| B --> D("$$x = \begin{cases} a &\text{if } b \\ c &\text{if } d \end{cases}$$") | ||
| C --> E("$$x(t)=c_1\begin{bmatrix}-\cos{t}+\sin{t}\\ 2\cos{t} \end{bmatrix}e^{2t}$$") | ||
| ``` | ||
|
|
||
| ```mermaid | ||
| graph LR | ||
| A["$$x^2$$"] -->|"$$\sqrt{x+3}$$"| B("$$\frac{1}{2}$$") | ||
| A -->|"$$\overbrace{a+b+c}^{\text{note}}$$"| C("$$\pi r^2$$") | ||
| B --> D("$$x = \begin{cases} a &\text{if } b \\ c &\text{if } d \end{cases}$$") | ||
| C --> E("$$x(t)=c_1\begin{bmatrix}-\cos{t}+\sin{t}\\ 2\cos{t} \end{bmatrix}e^{2t}$$") | ||
| ``` | ||
|
|
||
| ### Sequence | ||
|
|
||
| ```mermaid-example | ||
| sequenceDiagram | ||
| autonumber | ||
| participant 1 as $$\alpha$$ | ||
| participant 2 as $$\beta$$ | ||
| 1->>2: Solve: $$\sqrt{2+2}$$ | ||
| 2-->>1: Answer: $$2$$ | ||
| Note right of 2: $$\sqrt{2+2}=\sqrt{4}=2$$ | ||
| ``` | ||
|
|
||
| ```mermaid | ||
| sequenceDiagram | ||
| autonumber | ||
| participant 1 as $$\alpha$$ | ||
| participant 2 as $$\beta$$ | ||
| 1->>2: Solve: $$\sqrt{2+2}$$ | ||
| 2-->>1: Answer: $$2$$ | ||
| Note right of 2: $$\sqrt{2+2}=\sqrt{4}=2$$ | ||
| ``` | ||
|
|
||
| ## Legacy Support | ||
|
|
||
| By default, MathML is used for rendering mathematical expressions. If you have users on [unsupported browsers](https://caniuse.com/?search=mathml), `legacyMathML` can be set in the config to fall back to CSS rendering. Note that **you must provide KaTeX's stylesheets on your own** as they do not come bundled with Mermaid. | ||
|
|
||
| Example with legacy mode enabled (the latest version of KaTeX's stylesheet can be found on their [docs](https://katex.org/docs/browser.html)): | ||
|
|
||
| ```html | ||
| <!DOCTYPE html> | ||
| <!-- KaTeX requires the use of the HTML5 doctype. Without it, KaTeX may not render properly --> | ||
| <html lang="en"> | ||
| <head> | ||
| <!-- Please ensure the stylesheet's version matches with the KaTeX version in your package-lock --> | ||
| <link | ||
| rel="stylesheet" | ||
| href="https://cdn.jsdelivr.net/npm/katex@{version_number}/dist/katex.min.css" | ||
| integrity="sha384-{hash}" | ||
| crossorigin="anonymous" | ||
| /> | ||
| </head> | ||
|
|
||
| <body> | ||
| <script type="module"> | ||
| import mermaid from './mermaid.esm.mjs'; | ||
| mermaid.initialize({ | ||
| legacyMathML: true, | ||
| }); | ||
| </script> | ||
| </body> | ||
| </html> | ||
| ``` |
