# Welcome to the Highcharts Gantt JS (gantt) Options Reference

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

# chart.type

The default series type for the chart. Can be any of the chart types listed under plotOptions and series or can be a series provided by an additional module.

In TypeScript this option has no effect in sense of typing and instead the `type` option must always be set in the series.
