Introduction
chartjs-adapter-intl
is a date adapter for Chart.js that uses the native Intl.DateTimeFormat
API for date formatting and parsing.
Requires Chart.js 3.0.0 or later.
Note: once loaded, this adapter overrides the default date-adapter provided in Chart.js (as a side effect).
Installation
You can install this adapter via pnpm:
pnpm install chartjs-adapter-intl
via npm:
npm add chartjs-adapter-intl
via yarn:
yarn add chartjs-adapter-intl
CDN
By default, https://cdn.jsdelivr.net/npm/chartjs-adapter-intl
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@^3"></script>
<script src="https://cdn.jsdelivr.net/npm/chartjs-adapter-intl"></script>
