AnyChart JavaScript Gantt Chart provides built-in and custom data grid column formatting presets, making it easy to display dates, percentages, and financial values in the desired format.
This sample builds a project Gantt chart and adds seven data-grid columns, each using a different formatting preset: Common Log date, ISO-8601 date, US Short date, DMY-dots date, percent, and financial. A final column uses a fully custom formatter function that styles numbers, booleans, and strings with bold green underlined text and a custom width.
See the Gantt Chart documentation for all configuration options.
