Welcome to the Highcharts JS (highcharts) 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.

plotOptions.item.sonification.defaultSpeechOptions.mapping.time

Time mapping determines what time each point plays. It is defined as an offset in milliseconds, where 0 means it plays immediately when the chart is sonified.

By default time is mapped to x, meaning points with the lowest x value plays first, and points with the highest x value plays last.

Can be set to a fixed value, a prop to map to, a function, or a mapping object.
