# 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.

# sonification.showCrosshair

Show X and Y axis crosshairs (if they exist) as the chart plays.

Note that if multiple tracks that play at different times try to show the crosshairs, it can be glitchy, so it is recommended in those cases to turn this on/off for individual tracks using the showPlayMarker option.
