jqChart for ASP.NET Web Forms comes with a large number of predefined language packs and settings for almost all popular languages. They are located in the installation package, in the /js/i18n folder. Language packs are in the form of javascript files, containing definitions for all strings in the chart that can be localized.

In order to use a particular language pack, you need to include the javascript language pack to the head of your page, after the jQuery library reference (since language packs depend on jQuery) and after referencing the jqChart javascript file.

For detailed implementation, please take a look at the Aspx code tab.
