Welcome to the Highcharts Gantt JS (gantt) Options Reference

These pages outline the chart configuration options, and the methods and properties of Highcharts objects.

Feel free to search this API through the search bar or the navigation tree in the sidebar.


A full set of chart options to apply as overrides to the general chart options. The chart options are applied when the given rule is active.

A special case is configuration objects that take arrays, for example xAxis, yAxis or series. For these collections, an id option is used to map the new option set to an existing object. If an existing object of the same id is not found, the item of the same index updated. So for example, setting chartOptions with two series items without an id, will cause the existing chart's two series to be updated with respective options.
