# Locale
For applications where the numbers of ticks on scales must be formatted accordingly with a language sensitive number formatting, you can enable this kind of formatting by setting the locale option.
The locale is a string that is a Unicode BCP 47 locale identifier (opens new window).
A Unicode BCP 47 locale identifier consists of
- a language code,
 - (optionally) a script code,
 - (optionally) a region (or country) code,
 - (optionally) one or more variant codes, and
 - (optionally) one or more extension sequences,
 
with all present components separated by hyphens.
By default, the chart is using the default locale of the platform which is running on.
