plotOptions.variablepie.sonification.defaultInstrumentOptions.mapping

Mapping options for the audio parameters.

All parameters can be either:

• A string, referencing a point property to map to.
• A number, setting the value of the audio parameter directly.
• A callback function, returning the value programmatically.
• An object defining detailed configuration of the mapping.

If a function is used, it should return the desired value for the audio parameter. The function is called for each audio event to be played, and receives a context object parameter with time, and potentially point and value depending on the track. point is available if the audio event is related to a data point, and value is available if the track is used for a context track using valueInterval.
