This adapter allows the use of Luxon with Chart.js. Luxon provides built-in support for time zones and internationalization.
Requires Chart.js 2.8.0 or later and Luxon 1.0.0 or later.
Note: once loaded, this adapter overrides the default date-adapter provided in Chart.js (as a side-effect).
npm install luxon chartjs-adapter-luxon --save
import {Chart} from 'chart.js'; import 'chartjs-adapter-luxon';
By default, https://cdn.jsdelivr.net/npm/chartjs-adapter-luxon
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/luxon@^2"></script> <script src="https://cdn.jsdelivr.net/npm/chartjs-adapter-luxon@^1"></script>
Read more about jsDelivr versioning on their website.
Any date adapter options in the chart configuration will be passed through to Luxon's factory functions.
The following table describes the supported options that these functions accept.
Namespace: options.scales[scaleId].adapters.date
locale
string
undefined
Set a locale to use on the resulting DateTime
instance. If not set, the adapter will use the locale, defined at chart options level. By default, Luxon uses the system's locale. See Intl
locale. numberingSystem
string
undefined
Set the numbering system to set on the resulting DateTime
instance. See Luxon and Intl
numberingSystem documentation. outputCalendar
string
undefined
Set the output calendar to set on the resulting DateTime
instance. See Luxon and Intl
calendar documentation. setZone
boolean
undefined
Override the zone with a zone specified in the string itself, if it specifies one. By default, Luxon uses options.setZone=false
. zone
string
|Zone
undefined
Set the zone to place the DateTime
into. By default, Luxon uses options.zone='local'
. See Luxon and Intl
timeZone documentation.
Read the Chart.js documention for other possible date/time related options. For example, the time scale time.*
options can be overridden using the Luxon formats.
