README

Plotly.js is a standalone Javascript data visualization library, and it also powers the Python and R modules named plotly in those respective ecosystems (referred to as Plotly.py and Plotly.R).

Plotly.js can be used to produce dozens of chart types and visualizations, including statistical charts, 3D graphs, scientific charts, SVG and tile maps, financial charts and more.

Contact us for Plotly.js consulting, dashboard development, application integration, and feature additions.

Table of contents

Load as a node module

Install a ready-to-use distributed bundle

npm i --save plotly.js-dist-min

and use import or require in node.js

// ES6 module
import Plotly from 'plotly.js-dist-min'

// CommonJS
var Plotly = require('plotly.js-dist-min')

You may also consider using plotly.js-dist if you prefer using an unminified package.

Load via script tag

The script HTML element

In the examples below Plotly object is added to the window scope by script. The newPlot method is then used to draw an interactive figure as described by data and layout into the desired div here named gd. As demonstrated in the example above basic knowledge of html and JSON syntax is enough to get started i.e. with/without JavaScript! To learn and build more with plotly.js please visit plotly.js documentation.

<head>
    <script src="https://cdn.plot.ly/plotly-3.0.0-rc.0.min.js" charset="utf-8"></script>
</head>
<body>
    <div id="gd"></div>

    <script>
        Plotly.newPlot("gd", /* JSON object */ {
            "data": [{ "y": [1, 2, 3] }],
            "layout": { "width": 600, "height": 400}
        })
    </script>
</body>

Alternatively you may consider using native ES6 import in the script tag.

<script type="module">
    import "https://cdn.plot.ly/plotly-3.0.0-rc.0.min.js"
    Plotly.newPlot("gd", [{ y: [1, 2, 3] }])
</script>

Fastly supports Plotly.js with free CDN service. Read more at https://www.fastly.com/open-source.

Un-minified versions are also available on CDN

While non-minified source files may contain characters outside UTF-8, it is recommended that you specify the charset when loading those bundles.

<script src="https://cdn.plot.ly/plotly-3.0.0-rc.0.js" charset="utf-8"></script>

Please note that as of v2 the "plotly-latest" outputs (e.g. https://cdn.plot.ly/plotly-latest.min.js) will no longer be updated on the CDN, and will stay at the last v1 patch v1.58.5. Therefore, to use the CDN with plotly.js v2 and higher, you must specify an exact plotly.js version.

MathJax

You could load either version two or version three of MathJax files, for example:

<script src="https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.5/MathJax.js?config=TeX-AMS-MML_SVG.js"></script>
<script src="https://cdn.jsdelivr.net/npm/mathjax@3.2.2/es5/tex-svg.js"></script>

When using MathJax version 3, it is also possible to use chtml output on the other parts of the page in addition to svg output for the plotly graph. Please refer to devtools/test_dashboard/index-mathjax3chtml.html to see an example.

Need to have several WebGL graphs on a page?

You may simply load virtual-webgl script for WebGL 1 (not WebGL 2) before loading other scripts.

<script src="https://unpkg.com/virtual-webgl@1.0.6/src/virtual-webgl.js"></script>

Bundles

There are two kinds of plotly.js bundles:

  1. Complete and partial official bundles that are distributed to npm and the CDN, described in the dist README.
  2. Custom bundles you can create yourself to optimize the size of bundle depending on your needs. Please visit CUSTOM_BUNDLE for more information.

Alternative ways to load and build plotly.js

If your library needs to bundle or directly load plotly.js/lib/index.js or parts of its modules similar to index-basic in some other way than via an official or a custom bundle, or in case you want to tweak the default build configurations, then please visit BUILDING.md.
