chartjs-adapter-moment

Overview

This adapter allows the use of Moment.js with Chart.js. Moment.js is a very heavy library and thus not recommended for client-side development. However, it was previously the only library supported by Chart.js and so continues to be supported. You may prefer chartjs-adapter-date-fns for a minimal bundle size or chartjs-adapter-luxon for larger bundle size with additional functionality included such as i18n and time zone support.

Requires Chart.js 2.8.0 or later and Moment.js 2.0.0 or later.

Note: once loaded, this adapter overrides the default date-adapter provided in Chart.js (as a side-effect).

Installation

npm

npm install moment chartjs-adapter-moment --save

import Chart from 'chart.js';
import 'chartjs-adapter-moment';

CDN

By default, https://cdn.jsdelivr.net/npm/chartjs-adapter-moment returns the latest (minified) version, however it's highly recommended to always specify a version in order to avoid breaking changes. This can be achieved by appending @{version} to the URL:

<script src="https://cdn.jsdelivr.net/npm/chart.js@2.9.3"></script>
<script src="https://cdn.jsdelivr.net/npm/moment@2.27.0"></script>
<script src="https://cdn.jsdelivr.net/npm/chartjs-adapter-moment@0.1.1"></script>

Read the Chart.js documention for possible date/time related options. For example, the time scale time.* options can be overridden using the Moment formats.

> npm install

The following commands will then be available from the repository root:

> gulp build            // build dist files
> gulp build --watch    // build and watch for changes
> gulp lint             // perform code linting
