Highcharts v12 adds lang.locale to enable regional date and number formatting, defaulting to the browser's language if undefined.
Highcharts is a JavaScript charting framework that allows web developers and data analysts to generate dynamic, visually appealing charts and graphs for websites and web applications. It can display a variety of chart types, including line, spline, area, column, bar, pie, scatter, and many more. Highcharts is well-known for its ease of use, rich documentation, and ability to handle huge datasets efficiently. Features include responsive design, accessibility support, and cross-browser compatibility. Its customization capabilities allow users to create bespoke data visualizations that increase engagement and provide insightful data presentations.
Highcharts v12 introduces the lang.locale option, enabling locale-aware formatting for dates and numbers in charts. This option allows you to define the locale for all charts on a page or set it individually per chart. If no locale is specified, the chart automatically defaults to the page’s or browser’s language settings. Utilizing the browser’s Intl object, lang.locale ensures that dates and numbers are formatted correctly, not only replacing elements like month and weekday names but also structuring entire date expressions according to the selected locale. For instance, American English (en-US) formats a date as January 1, 2025, while British English (en-GB) displays it as 1 January 2025.
