Docsify is a powerful and easy-to-use documentation site generator. You can quickly publish your documentation on github, ...
Some strange guys want to display diagrams inside documentation. Vega/vegalite can be a pleasant way to draw its.
This documentation explains how to integrate vega/vegalite diagrams into your docsify documentation.
Add blocks of code in your markdown with vega
or vegalite
syntax property.
```vega
your vega code
```
```vegalite
your vegalite code
```
You can write either json or url to external code :
```vega
{
"$schema": "https://vega.github.io/schema/vega-lite/v5.json",
"width": "800",
"height": "600",
"data": {
...
}
}
```
```vega
https://raw.githubusercontent.com/vega/vega/master/docs/examples/bar-chart.vg.json
```
In your docsify index.html your must add following code :
window.$docsify = {
...
}
// import vega
// <script src="//cdn.jsdelivr.net/npm/vega@5"></script>
// <script src="//cdn.jsdelivr.net/npm/vega-lite@5"></script>
// <script src="//cdn.jsdelivr.net/npm/vega-embed@6"></script>
// <script src="//cdn.jsdelivr.net/gh/jerCarre/vega_docsify@v1.1/lib/docsivega.js"></script>
According to official vega documentation you can add extra options for all diagrams :
window.$docsify = {
...
vegalite: {
actions: {editor: true, source: true, compiled: false}
}
...
}
// import vega
// <script src="//cdn.jsdelivr.net/npm/vega@5"></script>
// <script src="//cdn.jsdelivr.net/npm/vega-lite@5"></script>
// <script src="//cdn.jsdelivr.net/npm/vega-embed@6"></script>
// <script src="//cdn.jsdelivr.net/gh/jerCarre/vega_docsify@v1.1/lib/docsivega.js"></script>
