Localization in Angular Stock chart component

27 Sep 20234 minutes to read

Localization library allows to localize the default text content of StockChart. In stock chart component, it has the static text on some features(like zooming toolbars) and this can be changed to any other culture(Arabic, Deutsch, French, etc) by defining the locale value and translation object.

Locale key words	Text to display
Zoom	Zoom
ZoomIn	ZoomIn
ZoomOut	ZoomOut
Reset	Reset
Pan	Pan
ResetZoom	Reset Zoom

To load translation object in an application use load function of L10n class.

For more information about localization, refer this localization
