Week numbers are calculated based on locales. For this to properly work, the timeline must be loaded with a version
|
|
of moment.js including locales.</p>
|
|
<p>To set a locale for the timeline, specify the option
|
|
<code>{locale: STRING}</code>.</p>
|
|
<p>To set the scale to use week numbers, use for example <code>{scale: 'week', step: 1}</code>.</p>
|
|
<p>The following timeline is initialized with the 'de' locale and items are added with locally localized moment.js
|
|
objects. The timeline locale can be switched to another locale at runtime. If you choose the 'en' locale, the week
|
|
numbers will be calculated according to the US week calendar numbering scheme.</p>
