# plotOptions.series.sonification.tracks.mapping.pan

Pan refers to the stereo panning position of the sound. It is defined from -1 (left) to 1 (right).

By default it is mapped to `x`, making the sound move from left to right as the chart plays.

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