# 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.

# yAxis

The Y axis or value axis. Normally this is the vertical axis, though if the chart is inverted this is the horizontal axis. In case of multiple axes, the yAxis node is an array of configuration objects.

See the Axis object for programmatic access to the axis.
