Welcome to the Highcharts Stock JS (highstock) 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.


Define a condition for when a track should be active and not.

Can either be a function callback or a configuration object.

If a function is used, it should return a boolean for whether or not the track should be active. The function is called for each audio event, and receives a parameter object with time, and potentially point and value properties depending on the track. point is available if the audio event is related to a data point. value is available if the track is used as a context track, and valueInterval is used.
